For console players, 2020 is undoubtedly a happy year. After a long wait, Microsoft and Sony will each launch a new generation of home consoles Xbox Series X and PlayStation 5 (hereinafter referred to as XSX and PS5) at the end of this year, which will kick off the new era of console games? What are the key difference between PS5 and Xbox Series X, which one is better to choose? Here we go:
PS5 vs Xbox Series X: key difference
1. Theoretical performance: Xbox seizes the advantage
Like the eighth generation, both Sony and Microsoft used AMD's custom processors for the console market. The previous-generation AMD Jaguar processor is based on the simplified Bulldozer (dozer) micro-architecture, and this generation of processors uses the Zen 2 architecture that helps AMD salted fish turn over, and the same-frequency performance has made great progress.
Both PS5 and Xbox Series X are 8-core Zen 2 CPUs, and Microsoft has a slightly higher frequency. Compared with PS5, there is also SMT hyper-threading technology support. If the game is optimized, it should have a clear advantage when running on Xbox Series X.

PS5 adopts a dynamic frequency design (according to the load, the CPU frequency can fluctuate within a certain range). In some scenarios, it can reduce CPU power consumption and allocate power consumption to the graphics card.
In terms of GPU, PS5 is more passive. Remember when PS4 and Xbox One were released in 2013, XBox lost to PS4 in GPU performance competition, and had to overclock the processor before the sale to minimize the gap. Despite this, the previous Xbox One still seemed to be unable to run 1080P games, and the resolution could only be set to 900P to be comparable to PS4.
When Microsoft released the Xbox One X in 2017, it improved the GPU CU from 12 to 40 at a stretch, and the single-precision floating point reached 6TFLOPS, taking the first place in host performance.
The performance-oriented style also has obvious traces on the Xbox Series X. The Xbox Series X 52CU has 16 more GPU units than the PS5 36CU, bringing a theoretical 16% performance advantage.
In addition to the gap in the number of CUs, we can also see that the GPU frequency of PS5 has reached 2.23GHz, which is much higher than the 1.825GHz of Xbox.
Higher frequency will inevitably bring higher power consumption and heat dissipation pressure. Fortunately, PS5 supports floating frequency in the CPU, which can reduce the heat dissipation pressure caused by high frequency in some scenarios. Sony makes the GPU frequency up to 2.23GHz, indicating that they are confident in the thermal design of PS5 (of course, the possibility of PS5 cooling overturning is not ruled out).
On the other hand, PS5 also allows us to see the potential of the RDNA2 architecture, which can exceed such a high frequency. I believe that the upcoming RX 6000 series graphics cards will also perform well.
In addition, the RDNA2 architecture also supports ray tracing, which means that this generation of game consoles will popularize optical chase. In the future, optical chase will become the standard effect of 3A masterpieces.
2.IO performance: PS5 leads the field
In addition to the APU performance difference, the Xbox Series X and PS5 are also a little different, that is SSD.

After so many years of development, SSD has become the standard storage device in PC. In the PS4 era, the first thing that many players get when they get a game console is to replace it with an SSD. After all, the IO bottleneck of the HDD is too serious. In order to reduce the impact of disk reading on the game experience, many games will put a thin corridor in two large scenes, and read the next one when the player passes through the gap.
The Xbox Series X uses a 1TB SSD with IO throughput of 2.4GB/s (raw) and 4.8GB/s (compressed). Compared with this, the PS5's SSD IO throughput has almost doubled, 5.5GB/s (raw), 8-9GB/s (compressed). Obviously, this will bring obvious advantages to Sony, especially in terms of game loading and scene switching.

What is PS5 SSD and its future: Write before PS5 release
The PS5 will be released in a few hours. I want to talk about the PS5 SSD before PS5 release. In this thread I'll try to make some simple analogy to compare the meaning of PS5 high-speed SSD. AIn addition, i wanna anticipate the mode of future games. I tried to simplify the analogy of PS5 SSD ...
