Review Of Amd Radeon Rx 5700 Xt

0

Introduction

The AMD’s Radeon RX 5700 XT is finally here after a long wait and a period of speculation, adding to the available collection of best graphics cards. It has a new RDNA architecture which helps improve its performance without consuming a lot of power and also with a reduced price to maintain the AMD competitiveness with Nvidia’s recent RTX 2060 Super which was launched last week. This is seen as AMD’s latest GPU architecture since the GCN (Graphics Card Next) which was launched in 2012. Our main aim here is to show you the performance of this new model as well as its latest features and how it matches up to the available competition from both the Nvidia and also from AMD.

The AMD focuses on enhancing efficiency and have upgraded the Compute Units (CUs) to help improve its utilization and performance, and shifted to TSMC’s 7nm process technology. We’ll have a quick review of the specs and compare it with the new RX 5700 models and other several other AMD of the previous generation of GPUs:

Design

All the three RX 5700 models make use of similar Navi 10 GPU, in the 5700 XT cards the chips are fully enabled while the RX 5700 does not enable four CUs and 256 cores.  The clockspeed is also different for the GPUs, but the GDDR6 memory in all the cases runs at 14Gbps (14GT/s). the die size of the new Navi 10 GPUs is quite larger than the previous Polaris GPUs, with just few CUs. Although, each of the CU has been worked on with the addition of a new RDNA architecture, despite the few cores/CUs the RX 5700 XT outperforms the Vega 64 easily without consuming much power.

The new addition of the Game clock by AMD has been reported to increase performance while using the boost clock rather than the game clock. The game clock is an estimate of the actual in-game clockspeeds of what will be seen in the RX 5700 family. This means the games will run at higher clockspeeds, which is a similar approach taken by Nvidia’s boost clock, while the AMD’s boost clock kind of the maximum that will be seen by the GPUs, although some GPUs may exceed the stated boost clock.

You might not need to compare GFLOPS due to the differences in their architecture but at the end only the gaming performance matters. For instance, the RX 5700 XT has the theoretical performance of 9754 GFLOPS whereas the Vega 64 has theoretical performance of 12665 GFLOPS. Although the Navi/RDNA architecture is a make up for that lack just as how Nvidia’s RTX 2060 Super together with its 7181 GFLOPS could end up providing better gaming result than what is shown by the numbers. Comparing the GFLOPS architecture is most time not necessary.

Reference model for the RX 5700 XT and the RX 5700 were provided by AMD for testing. Despite that the circuit boards, GPU, memory is quite similar, there are some differences in the design for cooling shroud.

The RX 5700 XT has some grooves on its shroud and also a curved section. This indent is there to help provide an extra airflow especially in confined space. Although we’re not really sure how this matters, and although this curviness might be seen as a manufacturing defect, but is actually a design for aesthetic purpose. Not everyone will like this design and there is also a provision of custom cards for partners in AMD which replaces the blower cooling with two or three fans.

The New cooling is better than the previous generation cards, says AMD.  This cooling system is not extremely loud like the Vega Cards but this is due to the lower power requirements and not necessarily any change in the design of the cooling system. Thermals and Idle noise is usually the same for most of the GPUs but game playing is totally a different matter. When compared to the RTX 2060 Super, the RX 5700 is also low in noise and makes use of just 25W of power at the outlet and about 11°C increase in temperature. Nevertheless, in this comparison Nvidia wins.

Nvidia also brought up the RTX 2060 model and also the RTX 2070 Super of recently. This model has more core than the non-super variants and an additional 2GB VRAM for the 2060 Super, the AMD also announced a drop in the price for the 5700 XT by $50 so as to match the Nvidia price on the RTX 2060 Super.

Due to the competition between the AMD and Nvidia anyone looking for new graphics will really gain. Due to the lack of a good RTX competitor in the previous year, this led to an increase in the prices of the RTX line. Due to the presence of Navi, Nvidia has reduced the price to be paid for a similar performance for example the 2060 Super produces similar performance as the 2070, while the 2070 Super is quite similar to the 2080.

Features

Although the price of the RX 5700 XT and the RTX 2060 Super is similar, the features, performance as well as the API support is not the same. AMD has chosen not to support ray tracing (either DirectX raytracing aka the DXR or the Vulkan-RT) in the Navi GPUs. There is no presence of hardware level RT acceleration and also no Tensor processing clusters to ensure AI and machine learning. Although it is possible for it to support DXR through Drivers and Shader calculations, AMD doesn’t make any provision for that. If you need an AMD GPU with a Support for DXR hardware, then you’ll have to wait for the Navi 20, which is found in the next generation of Xbox and other PlayStation consoles.

As regard the testing, we’ll make use of the standard GPU test bed. The overclocked Core i7-8700K which runs at 5.0GHz ensures that the CPU doesn’t pose any problem, it comes with DDR4-3200 CL14 memory and fast SSD storage for the same reason. In other midrange and budget GPUs the GPU bottlenecks is not really a problem. The RX 5700 and the Nvidia’s RTX cards, the performance of the CPU would be considered especially at 1080p.

We’ve used the latest drivers used for testing to benchmark, including retesting the older GPUs to make sure the results are up to date. The 430.86 drivers were used to test the Nvidia GPUs, except the two Super cards which makes use of 431.16. To test the AMD, the 19.16.2 drivers for the previous generation of GPUs, and new drivers of the RX 5700 cards. Although, the GPU could be retested with the latest drivers, this will require a full day for the GPU to be tested. There is certainly no time to do this as only a week is available for the test.

There is also an update on the selection of games we used in the GPU testing, and there was no use of DXR or DLSS for any of the benchmarks. This gave room for a reasonable comparison of the various GPUs, because AMD dies not support DXR presently. About 11 games used consisted of a mix of AMD and Nvidia promoted titles, like: Far cry 5, The Division 2, Far Cry 5, Strange Brigade, Total War: Warhammer 2 all have AMD branding, whereas Metro Exodus, Assassin’s Creed Odyssey, Shadow of the Tomb Raider are all promoted by Nvidia. The DirectX 12 was used in most case where it is available, except for Total War: Warhammer 2 where the “DX12 Beta” performed quite low in the Nvidia’s GPU.  When Vulkan’s performance was checked, we found that the DX12 was faster so it was then chosen.

Four settings were used to test each card: 1080p medium or its equivalent and 1080p/1440p/4k ultra except where it was noted otherwise. Each of the settings was tested several times over so as to make sure the result remains consistent and then the best score was used. The minimum FPS was calculated by adding all of the frame times above the 97 percentile and then divided by the number of frames, so we’re basically using the average of the minimum fps other than the absolute minimum. This makes it a worthy representation of the lower end of its performance scale other than just paying attention to the worst frame rate from a benchmark run. For the 1080p, one might easily assume that the graphics card is not the primary target, but in order to max out the capabilities of the 144Hz monitor, then the 1080p makes it quite easier than the 1440p.

Performance of the Radeon RX 5700 XT

We won’t waste a lot of time discussing the individual results, and you’ll be able to check it out using charts. Although there are some lapses in performance, but the overall performance and the positioning of the different GPUs makes sense.  The FPS of the RX 5700 XT was poor in several different games like the Shadow of War, Hitman 2, and in the Warhammer 2), but this is due to the new architecture and the launch driver. The chart is being updated, but generally, the RX 5700 XT is 5-10 percent faster than the RTX 2060 Super.

This difference is likely to increase when AMD makes improvement in their driver issues. Or if they don’t, The Strange Brigade performs quite higher than was expected and the updated drivers might help change that. Irrespective of this difference, the performance is quite close and hence shouldn’t be a deciding factor when choosing between the AMD and the Nvidia. The Nvidia supports the use of DXR and DLSS while the AMD is way faster but uses a lot of power and doesn’t support the DXR or DLSS.

In terms of value, there is none ahead of the RX 570. We’re not sure if AMD is developing Polaris GPUs, but the RX 570 manufactures a lot of it. The only issue is that the 570 is good for 1080p medium to a high quality gaming; there are a lot of different games that the 1080p ultra at the 60fps which doesn’t happen on the card. The 1080p ultra is well managed and handled by the RX 5700 XT, even at 1440p ultra. Although there are some games in which the settings will need to be dropped in order to maintain a 60fps at 1440p, like the Assassin’s creed. In other games, the 5700 XT get to reach 60fps and there are some cases it gets to 100fps. When the RX 5700 XT with a FreeSync display is paired, and a game which can hit 50fps will run smoothly.

After different marketing struggles over the years, the Nvidia has adopted the FreeSynch displays on its RTX and GTX cards. Unfortunately, the AMD can’t support FreeSync on a G-Sync display and the Nvidia has conducted several tests and found out that the FreeSync displays doesn’t meet some of its standards for the official G-Sync Compatible Certification, this is an advantage of the for AMD as well as the open FreeSync (Adaptive sync) standard.

Aside this, the RX 5700 XT comes in handy when it comes to manufacturing a completely new PC as another aspect of value. For the major three monetary market that was checked, the RX 5700 XT ranks the highest in the system value charts just above the 2070 Super, RX 5700 and the 2060 Super. When you intend to build a new gaming PC in the near future on a budget less than the whole PC, it will be nice you go for the high-end GPU like AMD’s RX 5700 XT or opt for one of the Nvidia’s new RTX Super cards.

Radeon RX 5700 XT is a worthy addition to the GPU market

There are lot of things that makes the AMD’s new Navi GPUs and RDNA architecture attractive.  In this model the efficiency and the performance is increased unlike the previous generation Vega and Polaris cards. This was possible thanks to the 7nm manufacturing process, and also due to the improvement in architecture and also their reduction in price contributed to the success.

The overall performance was nice. When the RX 5700 XT is compared with the RTX 2060 Super in terms of performance, the AMD was higher. However, the ray tracing won’t be available when you choose the AMD. Although it might not matter, but the issue as regard the increase in the number of games coming out that supports ray tracing makes it very important in the long term. The AMD still has some attractive features that need to be explored like the anti-lag, FidelityFX and the Radeon Image Sharpening which is used for games that doesn’t have the FidelityFX support.

Although some of those feature have not been looked into fully, or the overclocking of the RX 5700 XT checked, yet the new graphics cards are still amazing. Worthy of note is that the AMD is now in competition with the Nvidia’s lower tier RTX cards in terms of pricing as well as performance. Yet it cannot be compared with the RTX 2080 and the 2080 Ti, although there is no need for it right now. Some person might invest as high as 700$ or $1200 to get an extreme graphics cards, but other persons will be interested in getting $350-$400 high-end graphics card which can push 60-144fps at just 1080p/1440p.Those individuals won’t fail to grab the AMD’s Radeon RX 5700 XT and the option of getting three months of free access to Microsoft’s Xbox Game Pass (packed with Gears of War 5) this makes the deal more attractive. Although fancy ray tracing support will not be included, but this offer from AMD is worth it as it comes with an upgrade in new graphics which doesn’t need supporting Nvidia.
