Обзор видеокарты AMD Radeon RX 480

AMD Radeon RX 480 8Gb. Версия от HIS

С появлением новой игровой видеокарты RX 480 большинство геймеров задумались о том, чтобы обновить свой ПК, это не удивительно ведь такой производительности в этой ценовом не видели уже давно. AMD выпустила два решения RX 480 4GB которая стоит 199$ и RX 480 8GB которая обойдётся вам на 40$ дороже, давайте решим стоит ли оно того, и является ли различие в размерах памяти существенной разницей.

Характеристики Radeon RX 480

Как показывает практика 4 и 8 ГБ практически не отличаются, но память у 8Gb версии быстрее она 256 GB/сек, а у её младшей модели 224 GB/сек.

А теперь посмотрев на тесты:

Можно понять, что версия за 199$ немного проигрывает, в каждом тесте показывая результаты на 3-4% хуже, чем видеокарта за 240$. Но эти проценты явно не оправдывают наценку, ведь при работе видеокарты вы вряд ли почувствуете эти незначительные отличия, да и если взглянуть на системные требования современных игр, можно понять что 4Гб хватает с головой.

RX 480 4Gb — Unigine Heaven — Haswell RX 480 4Gb — Unigine Valley — Skylake RX 480 4Gb — Unigine Heaven — Skylake RX 480 4Gb — Unigine Valley — Haswell

А теперь перейдем к версии на 8GB. хотелось сказать что тактовая частота ограниченна планкой в 1266 Мгц, но это не придел чипа который создан по технологии 14 FiNFER. Сами AMD заверяют что переход между узлами с 28 нм на 14 нм поднял производительность видеокарты  в 1,8 раз, а что до оптимизации, её довели к соотношению 2,9. И сразу же в голову приходит сравнение с GeForce GTX 1070, которая с такой же мощностью обладая немного более вместительным GPU доходит до частоты 1683 Мгц.

Коротко поговорим о характеристиках RX 480:

  1. Архитектура — GCN 4-е поколение.
  2. Количество вычислительных блоков — 36.
  3. Потоковые процессы – 2304.
  4. Тактовые частоты. Базовая и ускорение – 1120 Мгц / 1266 Мгц.
  5. Пик производительности – достигает до 5,8 терафлопс.
  6. Тип памяти – GDDR
  7. Полоса пропуска памяти — 224 Гб и иногда выше.
  8. Стандартное потребление платы – 150 ВТ.
  9. Версия кабеля HDMI – 2,0.
  10. Максимальное разрешение — 5120×2880.
  11. Объем видеопамяти — 8192 Мб.
  12. Интерфейс — PCI-E 16x 3.0

Имеется поддержка Directx 12, а так же новая архитектура  Polaris c технологией AMD LiquidVR, дают ощущения глубокой реалистичности в сочетании с гарнитурами погружения  VR.

Производители и тесты

ASUS

ASUS предлагает два варианта дизайна RX 480, первый собственной разработки, разработанный для адаптеров ROG STRIX. И Asus Rog Strix-Rx480-O8g-Gaming с заводским разгоном частота которого составляет 1330 Мгц. Видеокарта имеет 8 гб памяти модели GDDR5, работающий на частоте 8000 Мгц. В видеокарте реализован гибридный режим работы системы охлаждения, это означает что в режиме покоя RX 480 бесшумна.

Радиатора достаточно для того чтобы поддерживать температуру GPU на отметке в 40-50 градусов. При тестирование видеокарты её пиковая температура не превысила 70 градусов, чтобы не допускать более сильного нагрева чипа вентиляторы крутились на скорости свыше 2000 об/мин. Также благодаря утилитам можно настроить свой режим охлаждения, но без соответствующих знаний этого делать не стоит.

Тестирование
  • Unigine Valley Benchmark — FPS: 53, Score 2228.
  • Unigine Heaven Benchmark — FPS: 52, Score 1313.
  • Benchmark Sky Diver – graphics score 4043
Игровые тесты:

Расширение во всех играх было установлено 1920×1080, а также были отключены функции VSync, все остальные настройки были установлены на максимальные. Процессор Intel Core i7-7700K с частотой 4.2GHz.

И вот какие результаты мы получили:
  • Crysis 3 – 52 Fps.
  • DOOM- 67 Fps.
  • Dying Light: — The Following 42 Fps.
  • GTA5 — 47 Fps.

Из этих данных можно сделать вывод что RX 480 прекрасно подходит для геймеров, и обеспечивает им хорошее погружение без тормозов.

Sapphire

Sapphire Radeon RX 480 Nitro+ 8Gb – у компании Sapphire есть несколько не совершенных моделей на архитектуре Polaris 10. Созданные на основе базы Nitro они совместили в себе качественное использование элементной базы и нерефернсной системы охлаждения, что в дальнейшем обеспечило этим видеокартам высокие характеристики, а так же низкий уровень шума, а также богатый набор функциональных возможностей. На модель 480 был установлен кулер DualX с новой технологией Quick Connect, данная технология позволяет быструю замену вентилятора, что позволяет проводить чистку в несколько раз быстрее, также как установлена утилита TriXX она отвечает за работоспособность вашего кулера, согласно словам разработчика если ваш кулер сломался, то связавшись с тех поддержкой вам могут выслать замену.

Тестирование

Sapphire Radeon RX 480 Nitro+ 8Gb получает несущественный заводской разгон, однако смотря на конкурентов это шаг вперёд. Частота возрастает от 1120 Мгц до 1160 Мгц а в режиме буста с 1266 до 1306. Также хотелось отметить, что в режиме когда видеокарта не нагружена система замедляет вентиляторы и температура держится на отметке 40-45 градусов, это уменьшает затраты электроэнергии. Чтобы дать оценку производительности был использован 3DMark Fire Strike, в результате проверки RX 480 Nitro+ 8Gb показала себя довольно неплохо частота чипа составила 1250-1285 Мгц,  при этом вентиляторы работали всего на 39% от совей пиковой мощности. Сама видеокарта при тесте работала тихо, а её температура составила 75-76 градусов.

  • Unigine Valley Benchmark — FPS: 54, Score 2265.
  • Unigine Heaven Benchmark — FPS: 53, Score 1358.
  • Benchmark Fire Strike – graphics score 13163.
В игровых тестах:

Процессор Intel Core i7-7700K с частотой 4.2GHz.

  • Crysis 3, Текстуры: Макс, MSAAx8, 1920×1080 – стабильные 55 fps, хотя бывали просадки до 40, в моменты когда было слишком много взрывов.
  • Ведьмак 3: Дикая охота, Высокие настройки,HairWorks выкл, 1920×1080 – показатели fps вирировались от 50 до 90 в местах разной загруженности таких как города. Делаем вывод вполне играбельно.
  • Rise Of Tomb Rider: 1920×1080 Высокие настройки графики – игра показывает среднее значение 41 fps, чего тоже вполне достаточно для комфортной игры.

Gigabyte

Лето 2016 года, именно в этот момент состоялся выход графических чипов AMD Polaris. Который стал первой ступенью Gigabyte при переходе на чипы 14 нм, и после этого им открылись новые возможности построенные на этой базе модели серии RX 480, RX 470, стали движущей силой производства в среднем ценовом сегменте.

Тестирование

Как показали тесты, на видеокарты с альтернативными системами охлаждения, сильно влияют тактовые частоты, а также температуры. На RX 480 установлен кулер WindForse  который справляется с температурой до 78 градусов, конечно это не самый низкий уровень, но и будем откровенны не самый высокий.  Важно чтобы температура не превышала критическое значение, иначе видеокарта может сгореть.

  • Unigine Valley Benchmark — FPS: 56, Score 2285.
  • Unigine Heaven Benchmark — FPS: 50, Score 1318.
  • Benchmark Fire Strike – graphics score 14163.
В игровых тестах:

Расширение во всех играх 1920×1080, настройки bestquality, все тесты в DirectX 11: Процессор Intel Core i7-7700K с частотой 4.2GHz.

  • Rise Of the Tomb Raider – 45 Fps.
  • Fallout 4 – 45 Fps.
  • The Witcher 3: Wild Hunt — 50 Fps.
  • BattleField 1 – 40 Fps.

Вывод

На данный момент Radeon RX 480 является лучшем решением в среднем ценовом сегменте, где соперничает с GTX 1060. Благодаря утилитам которые можно подстроить под свои нужды, спектр решаемый ею задач велик, она одинакова хороша, как и в играх, так и в работе с графикой. А так же если вы обладатель VR вы, без каких либо проблем можете погрузиться в виртуальную реальность так как мощности карты будет вполне достаточно для этого.

AMD Radeon RX 480 shoots for value at $200

Nvidia is clearly going after the high-end GPU market with Pascal GP104 cards, with GTX 1080 and GTX 1070 both delivering better than Titan X levels of performance in our testing. AMD's response with Polaris 10/11 won't be direct competition, but instead AMD is going after the mainstream market. We can't talk about everything we've been told right now, but much like what Nvidia did with the GTX 1070, AMD is releasing the following key details today.

Right off the bat, we see plenty of things that tell us about positioning. AMD lists 36 Compute Units, and unless they're changing things with Polaris, they've used 64 'shader cores' in every GCN CU to date, that would be 2304 cores. That's fewer CUs than the R9 390, but almost 30 percent more than the R9 380. The price is perhaps the most important aspect, however: starting at $199. Presumably that will be the 4GB model, with 8GB models carrying a moderate price premium—somewhere between $20 and $50 would be about right, given current 2GB vs. 4GB pricing.

The most important number in all of this right now is probably the TFLOPS, which AMD states as >5 TFLOPS. Again, that's about in line with the R9 390, at a significantly lower price and power level. If you're wondering about clock speeds, like Nvidia architectures, peak TFLOPS on GCN ends up being two 32-bit FLOPS (FLoating-point Operations Per Second) per core, times the clock speed. Working back from the >5 TFLOPS and CU number, we get a minimum estimate of 1085MHz. Except, the greater-than sign suggest that AMD hasn't finalized clock speed yet, so it could be 5.1 TFLOPS or 5.9 TFLOPS (~1280MHz) once the card hits retail.

On the memory side of things, like the GTX 1070, RX 480 will run GDDR5 at 8000 MT/s (2000MHz base, four bits per cycle). We might be tempted to complain about the 4GB and 8GB models, but at this level of performance, 8GB probably isn't going to be strictly necessary—and if you're willing to pay a bit more, you can still get it. The 256-bit bus is a large step down from the R9 390's 512-bit bus, and AMD hasn't officially stated whether they're doing any new forms of memory compression to help compensate.

The only other major item worth mentioning is that RX 480 will support DisplayPort 1.3 / 1.4 HDR, a step up from the DP 1.2 in current products. RX 480 will also be VR-ready, with what appears to be similar performance expectations relative to the R9 290/390 cards.

Looking at the bigger picture, those who were hoping to see AMD's Polaris take on Nvidia's Pascal chips will be disappointed. Rather than improving overall performance, AMD is going after the value-conscious gamers. There's nothing wrong with that, and AMD cites Mercury Research data showing 13.8 million people spent between $100 and $300 on graphics cards. Here's the thing: we've been able to get pretty much this level of performance with the GTX 970 and R9 290/390 cards for about a year and a half, only at prices closer to $300-$350.

Cutting the price by a third is great, but it mostly matters to those who haven't purchased a faster GPU during the past year or two. Much like our advice on the GTX 1070 preview, we recommend gamers look at skipping a generation—or two if you can manage—between graphics card upgrades. Some will buy a $600 card every two or three years, others will buy a $350-$400 card every few years, and still others will look at a $200-$250 card as a periodic upgrade.

So who should be most interested in making the upgrade to an RX 480 once it becomes available? Anyone currently running R7 370 or lower (HD 7870) could potentially double their gaming performance. Or another way of looking at it is that the RX 480 offers roughly the same performance potential as the old Radeon HD 6990 in a card that uses less than half as much power. But that card's five years old now. On the Nvidia side, if you're thinking about switching from team green to team red, GTX 760 and lower (GTX 670 and lower) potentially double performance, not to mention adding some new features and reducing power requirements.

We don't have hardware in hand yet, but that should come sometime before the official June 29 launch date, and there will be other new GPUs alongside the RX 480. And even though this may not have the excitement of a $380 Titan X equivalent, the current consoles have to get by on 1.3-1.84 TFLOPS, so now a $199 GPU will basically offer three times the performance potential of a PS4. Next time someone tries to tell you PC gaming is expensive, try putting a $200 GPU in any PC made in the past five years, and you have a much less costly console alternative.

AMD Radeon RX 480 Review

After four years of 28nm designs, Nvidia recently ushered in the 16nm process by launching today's top performing GPUs: the GeForce GTX 1080 and GTX 1070. In short, their performance was impressive, power consumption was amazing, and prices were... well, typical. Sadly, availability of these new cards has been underwhelming, leaving some consumers frustrated with the temporary hike in pricing.

Those who can afford a $400+ graphics card and actually managed to hunt down a Pascal GPU will no doubt be pleased. For the rest of us, or rather for the majority of us, we have been waiting for something else, and for most that something could be AMD's Radeon RX 480.

Touted as the perfect VR solution for the masses, AMD is hoping to claw back a bit of market share with the new Radeon RX 480 which is aimed at the mainstream $200-250 segment, with other affordable Polaris GPUs expected to follow.

Whether on purpose or forcefully so, AMD is flipping how they used to release new GPUs, starting with mainstream products this time and working up to the high-end stuff. This might make sense given the company's current market share predicament, though I personally feel the move to the 14nm process has almost forced AMD into this strategy. The process may need to mature before larger, more complex GPUs can be created in sufficient volumes.

Then again, with over 80% of the PC gaming market dominated by $100 - $300 graphics cards, this is where the bulk of the market share is won and lost. AMD's first strike will be made at the $200 price range ($240 for the 8GB model) with the RX 480.

This Polaris-based GPU is based on the 4th-generation GCN architecture, boasting up to 15% more performance per Compute Unit (CU) than GPUs using 2nd-gen GCN, according to AMD. Memory performance and compression has also been improved with an updated memory controller supporting GDDR5 at up to 8Gbps data rates for a memory bandwidth of 256GB/s.

For Polaris, AMD selected Samsung and Global Foundries' 14nm FinFET-based process, which is the densest foundry process available. FinFET transistors are crucial to reducing power consumption and enabling operating voltages that are 150mV lower than the previous generation, thereby cutting active power by 30% from a 1V baseline.

In contrast, Nvidia is using TSMC's 16nm FinFET-based process, so it will be interesting to see how they compare in terms of size and efficiency. Nvidia has had the upper hand in terms of efficiency for some time now and with Pascal proving to be its most efficient architecture yet, we are banking on big things from AMD.

Meet Polaris 10's Biggest GPU

So far we know there will be at least two GPUs based on the Polaris 10 die, the biggest of which is the 2304 Steam Processor-enabled Radeon RX 480.

The die measures just 232mm2, which is incredibly small for a GPU claiming 5.8 TFLOPS of compute power. In terms of physical size, the RX 480 GPU is close to the R7 370, a budget oriented GPU with just 1024 SPUs and 2 TFLOPS of compute power.

Compared to Nvidia's 16nm Pascal-based GTX 1080 and 1070 GPUs, the Radeon RX 480 is 26% smaller but of course it is targeting a lower performance tier.

Inside that die we have 2304 SPUs, 144 TMUs and 32 ROPs. Core specifications place the RX 480 between the Radeon R9 380X and R9 390. Naturally, it's meant to be more efficient, so that should help it close in on the beefier R9 390. In fact, also helping out here are the advanced clock speeds.

One of the biggest questions surrounding the RX 480 ahead of its launch regarded its operating frequency. The Pascal GPUs run no slower than 1.5GHz and can often be found operating at up to 1.8GHz out of the box using Nvidia's GPU Boost 3.0 technology.

AMD has been more conservative, clocking the Radeon RX 480 at just 1120MHz with a boost clock speed of 1266MHz. This means the RX 480 can operate up to 27% faster than the R9 390 in its stock configuration, which should help compensate for the 10% reduction in cores.

Still, compared to the R9 390, the RX 480 does have one other disadvantage: its memory interface. Even with AMD's generational efficiency improvements, we wonder how they plan to overcome the RX 480's ~30% decrease in memory bandwidth. While the previous generation R9 390 utilized a huge 512-bit wide memory bus allowing 384GB/s of bandwidth using relatively slow 1500MHz GDDR5 memory, the memory bus of the RX 480 has been halved to 256-bit. To close that gap the RX 480 makes use of faster GDDR5 memory clocked at 2000MHz.

We know the RX 480 has fewer cores than the R9 390, but they are clocked a bit higher. We also know that the die is extremely small and that improvements to efficiency have been made beyond the die shrink. All of this helps to explain the card's 150 watt TDP rating, which is some 45% lower than that of the R9 390, though it's concerning that this is the same rating given to the GTX 1070 and we expect that card to be considerably faster.

Pricing then will be the Radeon RX 480's key to success. The 8GB model that we are testing tody will cost $240, while a 4GB model will be available for just $200. Both support DirectX 12 along with OpenGL 4.5, OpenCL 2.0 and Vulkan 1.0. They also come with three DisplayPort 1.4 outputs with HDR support and a HDMI 2.0 port supporting 4K @ 60Hz.

AMD Radeon RX 480 'Forefathers Edition'

Unlike Nvidia, AMD won't be charging a premium for graphics cards using its reference cooler. It's also not giving anything a fancy name -- the reference card and cooler will be unofficially known as the AMD reference version, just as it has been in the past.

Design-wise the RX 480 reference card is minimalistic, there are no LED lights, no steel fan shrouds and no back plate. Borrowing its design from the previous-gen R9 380, the card looks nice. It has that Fury X look about it, without the liquid cooler hanging out the back. Instead you get a typical blower style fan that can draw in air from both sides, which can be useful in small cases.

The card measures 240mm long, though the PCB is just 177mm, so it should be easy for board partners to produce smaller cards right out of the gate. Whereas most R9 390 cards stretched at least 270mm long, we expect to see most RX 480s shaving 100mm off that length.

The RX 480 reference card is surprisingly light thanks to the use of a very small heatsink. So small that we'd only expected to see this on the lowest end gaming graphics cards. It will be interesting to see how hot the RX 480 runs. We're also curious to see how well the RX 480 overclocks. Considering AMD's recent history, we're not expecting great things, but I am hoping to be pleasantly surprised.

Power consumption should be relatively low going by the TDP rating and the use of a single 6-pin power connector. Even the older R9 380 required two 6-pin connectors, and you had to step down to the R7 370 before you found a single power connector. In fact, the PCB design and configuration looks more like a GeForce GTX 960. Onboard we find a 6+1 phase power design and eight GDDR5 memory chips for a total VRAM capacity of 8GB.

Finally, on to the benchmarks... !
