Zen Architecture Design 2 Things You Won’t Miss Out If You Attend Zen Architecture Design

Anyone watching the PC amplitude should be acquainted of how far AMD has appear in the aftermost brace of years. First with the barrage of their Zen CPU architecture, and afresh with Zen 2 and Zen 3, AMD has attempt aback up to actuality a appalling adversary for Intel. On the cartoon side, AMD has trailed bazaar baton NVIDIA for some time, although they are aggravating to accomplish apology with their new RDNA 2 cartoon architecture. Throughout all of this, AMD has been a basic in the animate space, accouterment the arrangement on a dent (SoC) powering both PlayStation and Xbox in the aftermost generation, and AMD’s architectonics wins accept connected for this new generation.

The big aberration for this bearing of animate is aloof how far AMD has appear with their CPU architecture. The Xbox One and its assorted revisions were powered eight AMD Jaguar CPU cores, at 1.75 GHz in the Xbox One and One S, and 2.3 GHz in the One X. Originally advised for small, low-power (and low-cost) systems, Jaguar was not the best CPU architectonics back it launched. And afterward the years back afresh confined as the affection of the aftermost bearing of consoles, Jaguar is absolutely activity the compression in 2020.

For the Xbox Series X|S lineup, Microsoft is afresh axis to AMD, and this time AMD is accessible and cat-and-mouse for Microsoft with their abundant added able Zen 2 CPU cores. In the case of the Xbox Series X, it is alms eight cores which will run at 3.8 GHz abiding on eight threads, or if the developer chooses to advantage Simultaneous Multithreading (SMT) and run sixteen threads, the processor will run at 3.6 GHz sustained. The lower-powered Series S offers the aforementioned cardinal of cores, but at 3.6 GHz / 3.4 GHz instead. Some may admiration why they do not bout the 4 GHz frequencies of the desktop counterparts, but consoles are added about constant adventures than aiguille achievement for a abbreviate time, so there is no turbo action in the Xbox.

To highlight aloof how abundant the aberration in achievement is amid the old Jaguar cores and AMD’s Zen 2 cores, we’ll alpha with a quick attending at Cinebnech R15. We accept been advantageous abundant to absolutely criterion the Xbox One SoC, with eight Jaguar cores active at 2.3 GHz, analogous the CPU abundance of the Xbox One X. Unfortunately, there is no exact replica of a Zen 2 processor to compare, but the Ryzen 7 3700X we activated offers the aforementioned eight cores and sixteen threads, although with a 4.4 GHz turbo frequency. So we’ll go advanced and extrapolate from the annual for AMD’s Ryzen 7 3700X CPU to annual for the slower clockspeeds of the new Xboxes,

XSX/XSS: Achievement Extrapolated From R7 3700X

Even adapted to somewhat bout the lower clockspeeds of the new consoles, the raw achievement from the new Zen 2 processor in the Series X is decidedly college than the approachable Xbox One X. Under Cinebench R15, single-threaded achievement is an absorbing 248% faster in the Series X, and 232% in the Series S. With up to 16 accoutrement accessible on the new consoles, multithreaded achievement offers an alike beyond benefit, at 414% faster in the Series X, and 386% faster in the Series S.

The antecedent bearing consoles were decidedly CPU limited, and while this was not consistently apparent in gameplay, the new bearing should be able to action abundant added immersive scenes with added activity on at any one time acknowledgment to the above CPU achievement increase – alike on Series S.

Of course, a above allotment of any animate is the cartoon processing unit. And alike added so than on the CPU side, Microsoft’s best of architectonics for the GPU ancillary of their animate SoCs is on the complete acid bend acknowledgment to AMD’s RDNA 2 architecture. In fact, at launch, the Xbox Series X will accept a added avant-garde AMD GPU than is accessible in any PC back AMD is not absolution RDNA 2 to the PC until 8 canicule afterwards the animate launch. RDNA 2 brings about some above upgrades to AMD’s GPU calendar which the Xbox aggregation will advantage to get the best out of the new hardware.

One of the bigger changes is the admittance of accouterments abutment for ray tracing, and as Microsoft has implemented DirectX Ray Archetype (DXR) support, the accouterments and software will assuredly be accessible in a animate for developers to advantage ray archetype for arena lighting. It will no agnosticism appear at a achievement penalty, as it is still a massively circuitous and computationally big-ticket assignment to use ray archetype for lighting, but for amateur that can handle the achievement loss, the affection of the lighting, reflections, and added furnishings should access tremendously.

Not to be outdone, shaders accept additionally apparent some amazing improvements with this generation, and the Xbox is demography advantage of all the improvements. Cobweb shaders acquiesce awful circuitous scenes to be rendered by accepting accoutrement cooperate, so bags of geometric altar can be black from a almost low cardinal of shaders. Imagine a bank area every atom of beach needs to be rendered. Back best of the grains of beach are similar, cobweb concealment allows for a cogent bulk of archetype to be avoided, after demography abroad from the all-embracing angel quality. There is a lot added to cobweb shaders than aloof this example, and they will crave new bold engines to booty advantage of the new shader processes, but we should alpha to see this in next-gen titles in the future.

RDNA 2 additionally brings Variable Rate Concealment (VRS) to the table, which allows developers to apply their assets area it is important. In any one scene, not all of the angel affectation is activity to be noticed, so VRS allows the developer to focus the achievement and angel affection on the genitalia of the arena that are the best important by abbreviation the concealment affection in those unimportant areas. This allows for college anatomy rates, alluringly after a apparent appulse on visuals. We are seeing this already implemented at barrage in amateur optimixed for the X|S lineup, such as Gears 5.

Adding to the new accouterments appearance is the capricious sizes of the dent GPUs central of the Xbox Series X|S. On the CPU side, the consoles are agnate in hardware, but on the GPU and added fronts, the Series S and Series X best absolutely diverge. The GPU is absolutely one of the best accessible changes here, as Microsoft has outfitted the Series X with a able-bodied 12 TFLOP GPU, with 52 CUs, and a 1.825 GHz frequency. This is hardly abate than the Radeon RX 6800 appear at the end of October but still bifold the TFLOPS of the Xbox One X (and added able on top of that). The Series S is a abundant abate GPU, with 20 CUs, 1.565 GHz frequency, and 4 TFLOPS total.

A analytical affection of any animate is the memory, and not alone how abundant in total, but how abundant is accessible to developers and how fast it is as well. Actuality the Series X and Series S bend decidedly again, with the X acutely focused on maximizing achievement to drive a 4K resolution, and the S acutely focused on price.

Both consoles affection GDDR6 memory, with 16 GB in the Xbox Series X, and 10 GB in the Xbox Series S. Acknowledgment to improvements in the dashboard design, Microsoft has bargain the arrangement aloof anamnesis to aloof 2.5 GB on the Series X, and 2 GB on the Series S, acceptation the consoles accept 13.5 GB and 8 GB of developer-accessible anamnesis respectively.

The Xbox Series X offers a 320-bit advanced arrangement bus, which is absolutely a bit narrower than the approachable Xbox One X, which had a 384-bit advanced bus. But, acknowledgment to GDDR6, the bandwidth is simultaniously both slightly bigger and abundant better. Which seems like an odd affair to say, but the Xbox Series X does not action a compatible anamnesis interface; instead there are altered channels of anamnesis acclamation altered amounts of anamnesis by advantage of application altered GDDR6 dent sizes (either 8 Gbit or 16 Gbit). This after-effects in an absurd best bandwidth, with 10 GB of the anamnesis accessible at up to 560 GB/s, and 6 GB of the anamnesis accessible at 336 GB/s. The Xbox One X, in comparison, offered 324 GB/s beyond its absolute anamnesis space. The higher-bandwidth allocation is absolutely chargeless for developers, with the Xbox arrangement aloof anamnesis active on the slower 6 GB, abrogation 3.5 GB of it accessible for developers.

The anamnesis bearings on the Series S is abundant altered though. This system, to save cost, and due to its lower achievement target, has aloof a 128-bit advanced bus, and while it still offers an absurd anamnesis layout, all 8 GB of developer aloof anamnesis is accessible at one speed, which is 224 GB/s. The 2 GB of system-reserved anamnesis is aloof 56 GB/s, but that should be affluence for the dashboard.
