Xbox One S – Revealed increase in performance – Eurogamer.pt

The Xbox One arrives today and we now have data on how fast is the new console. We also had access to a production model and had to test it for days. The Xbox One S has a 914MHz GPU, 853MHz compared to the previous one. It is an increase of 7.1% and the bandwidth increases ESRAM agreement, up to 218GB / s. Some games have differences – others run faster

The clock speed is one of the improvements in the Xbox One S, inserted a new system on chip package that adds support for games and mediates 4K.. According to Microsoft, it is necessary to increase the speed graphics core to support real-time rendering of non-HDR versions of the game in GameDVR functionality, streaming and images. Microsoft could have disabled this games non-HDR but chose not to do – it’s a little extra valuable asset. The difference is like an overclocked PC graphics compared to a normal. The Xbox One S runs as the normal console but there are scenarios in which the improvement is dramatic. – Much more than thought when Microsoft announced the specifications

“Some games (those that use dynamic resolution and / or ratios unlocked frames) can receive small improvements in performance, “says Albert Penello, senior director in the management and product planning at Microsoft. “Our internal tests have shown that it is small, and only measurable in some games, we do not want to become one of the attractions of the new console key.”

It should be? In the video below see the results of our tests but the conclusion is that at worst the Xbox One S operates as normal Xbox One. At best, we see a 9fps difference between the two. As Penello, the difference arises primarily in games with ratio of free frames but the bottom line is that even a title to fixed 30fps will have improvements to Xbox One original can not maintain the target performance.

An analysis of the GPU of the Xbox One S, compared with the original. It is faster, but how fast – and improves gameplay

First it should be noted that we use an Xbox original One provided by Micrsoft beside the 2TB version of the new Xbox One S. to ensure parity, all games run from an SSD Samsung 250GB on an external box via USB 3.0. This was done so that the storage is not a funnel and focus on performance capabilities of the processor.

We chose Project Cars that target 60fps but at a track in Monaco to rain and full of vehicles, rarely succeeds. A heavy load for the GPU, with many intensive alpha effects on bandwidth – processed by ESRAM believe. Using the repeat functionality can directly compare the rendering load the sessions. The result? An increase of 7% may not sound like much but it’s average. At the time, the differential can be as high as 5fps.

Restart to repeat the perspective of the third person in pursuit of camera – set angle – the performance rises by 11%, with a maximum delta at the time of 9fps. By examining sequences see a variation in the use of alpha effects – the storm is random – but the improvement is substantial, and repeats. This is the increase in the specifications at its best, a scenario which we have created to make the most of the faster clock Xbox One S, is not insignificant.

CPU	1.75GHz AMD Jaguar eight cores	1.75GHz AMD Jaguar eight cores
GPU	12 computational units	12 computational units
GPU – clock speed	914MHz	853MHz
computational Performance	1.4TF	1.31TF
ESRAM – bandwidth	219GB / s	204GB / s

Then we went to Hitman. You have the option of running the fixed or unlocked 30fps with v-sync. This is the closest we have as a comparative test between PS4 and Xbox One, demonstrating the weaknesses and strengths of each. In a direct comparison, the Xbox One S is 6.1% faster than the original. The despite the gameplay 100% compared not be fixed and would like, the differential increases to 8.1%.

you may be thinking that Microsoft should think again about this not be one of the main attractions. However, the improvement in performance is very sensitive to the context. Not all of the performance limitations are based on the GPU. The level of Paris in Hitman is full of NPCs and all these characters, simulated AI and animation are not cheap. The limitation on the performance here is due to the CPU, and see unfold sequence makes it interesting to see how the Xbox One S is above the Xbox One and then back to parity in a fascinating battle bottlenecks. We must say that at this level, the original Xbox One is in front of the PS4 by 9%.

Resident Evil 5 Remastered has targeted 1080p60 but fails regularly. There is an increase in performance on Xbox One S but only in areas related to the GPU – the minority according to our tests at the beginning of the game. The average increase in performance falls to only 2.5%. The lesson is that despite the GPU speeds have increased with an effect on bandwidth ESRAM, the CPU is the same -. As Microsoft had confirmed

Picking up games that target 30fps, as Rise of the Tomb Raider and Batman: Arkham Knight, seek possible improvements in performance and found that in the village of Geothermal Valley in Rise of the Tomb Raider, the Xbox One S softens some of the falls and reduces the screen-tear. Low performance for 28fps in full of NPCs scene in the original Xbox One but Xbox One S remains the perfect 30fps. It’s nothing out of this world but makes it more polished.

Arkham Knight is more curious. We have less screen-tear in kinematics that use the motor over Gotham, but are the sections of the Batmobile that reveal more because we have tearing and drops in frame rate. Frame rate increases in our tests on 4% but more noticeable is the reduction of jitter in frames times. The game is smoother, though not anything extraordinary, is an improvement.

Do buy an Xbox One S? It is a much improved console, as tells us Richard in this video.

The last test was Fallout 4, which will certainly benefit from the extra refinement offered by the increase in GPU Xbox One S but amazingly is same on both consoles. In some cases, the drops in frame-rate are literally identical, suggesting a bottleneck in memory or CPU. – Something that additional GPU power will not fix

We also tested the backward compatibility. Also here you will be more likely to see improvements in games running at 60fps and fail to consistent performance. Falls below 30fps in Alan Wake’s American Nightmare were reduced on Xbox One S. GPU power is not the problem in backward compatibility, more is the virtualization of the Xbox 360 CPU cores, so we believe that improvements in games with real problems performance (Mass Effect, Halo: Reach, etc.) are unlikely but it is good to know that the increase in graphic watch applies to all areas of the system

There are scenarios in which the increase in GPU and bandwidth ESRAM memory offer a momentary gain but in a world of locked games at 30fps, the increase in has less impact printing provision, in the form of a firmer locking the frame-rate scenarios focused on the GPU. The best performance in the new console is fascinating to highlight but in the real world, the Xbox One S simply added an additional level of consistency – some will notice and appreciate, others to the may want to, but it is also possible that many more or repair it.

the move to the production process 16nm FinFET TSMC for the revised SoC Xbox One leaves us to think about how far could this processor to be taken in view of the impressive increases in visas performance in Pascal processors Nvidia made on the same node. And if those two extra computational units in the design were reactivated? Probably never know of course that will never happen but would love to test prototypes with upclock that Microsoft could have in their laboratories.
