Also, what gpu and processor combo would match the XSX performance?
In: 2
Consoles are much more optimized since the hardware is already known and consistent
Consoles are sold at a loss with the expectation that games and accessories make up for it
Consoles don’t run ‘true’ 4k, they render at a lower resolution and upscale to mimic 4k
I’m not sure about Xbox Series X specifically, but they closest would likely be around 3060-3070 territory
They typically run lower graphical settings such as low-high, compared to desktops
Consoles like Xbox Series X are highly optimized – games are developed for specific, unchanging hardware. This allows every bit of performance to be squeezed out, unlike PCs where components and configurations vary greatly.
To match the Xbox Series X, you’d need a GPU and CPU combo that’s roughly equivalent to a custom AMD Zen 2 eight-core processor and a RDNA 2 GPU. This could be something like a Ryzen 7 3700X and a Radeon RX 6700 XT, although exact performance will depend on many other factors like cooling, power supply, and more.
Very few games run on the xbox series X in 4K. Usually it’s something lik 1440p or 1080p that is then upscaled to 4K.
Specs are hard to compare since consoles have unified system and graphics memory but it’s thought to be around an AMD 3700x but without the turbo and 6650 Xt with 16 Gb memory shared between them.
Also one advantage of having the console is that you can optimise more since everyone is runnign the exact same hardware. So might need to bump that GPU up a little bit. Still you can think of it as almost every 4K game is running some version of AMDs FSR or otherwise running a simple upscale on a lower resolution image.
They don’t, for one. Many games are not true 4K. They render lower and upscale it. Not all of them, but a lot.
Firstly, because the Xbox Series X is one bit of hardware. Every developer knows every Series X is the same, so they can do bits of optimisation that’s simply not possible on PC, because gaming PCs have basically an infinite amount of possible hardware configurations.
Secondly, consoles usually sell at a loss. Sony, Microsoft and Nintendo can sell you a console at less than it costs to manufacture, because they can then make the money back on games and accessories. But Nvidia or Intel aren’t selling you games, they need to sell you your graphics card at a profit. So a console generally works out cheaper.
As a side note, this is one of the reasons for the Xbox 360’s red ring of death. Microsoft insisted on selling the 360 at a profit, which necessitated making it as cheaply as possible.
To explain your second question, looking up the Xbox Series X’s GPU on TechPowerUp, and comparing it to RDNA 2 series GPUs (Because the GPU and CPU were both made by AMD), 2 came to mind when looking at shading units, TMUs, and ROPs. Those are basically things that help the main GPU die render things, like shadows.
The Xbox Series X’s Shader/TMU/ROP count comes out to 3328/208/64.
No existing RDNA 2 GPU has that exact amount, but we can guess.
Two that would match closely would be the Radeon Pro W6800 and RX 6800, both with 3840/240/96.
Now, let’s look at raw performance, with both FP16 and FP32 performance, which are measured in TFLOPS, or teraFLOPS. The term “FLOPS” is an acronym for “Floating Point Operations Per Second”.
As a baseline, the Series X gpu would have 24.29 FLOPS in FP16 perforance, and 15.12 in FP32.
The Radeon Pro W6800 has 35.64 TFLOPS of performance in FP16, with 17.82 TFLOPS of FP32.
The RX 6800 has 32.33 TFLOPS in FP16, and 16.17 in FP32.
Including the other theoretical performance benchmarks, which are “Pixel rate”, how many pixels the GPU can throw out per second, “Texture rate” which is the same for textures . (I don’t know if this is correct, please let me know if not), and FP64 performance. FP16, FP32, and FP64 are all floating-point calculations that take up 16 bits, 32 bits, and 64 bits respectively. The CPU needs lots of these, but the GPU could use some for, say, bruteforcing data to try to generate a console ID.
I won’t include these mentioned above, because this post is already getting long enough.
Comparing between the RX 6800 and the Xbox Series X’s GPU, it would be safe to say that the Series X has a nerfed RX 6800 in it.
Now for CPU, I’m not sure, but I believe it is a Ryzen of sorts.
Edit: Posts from u/prasiatko, and u/jowie7979 said the CPU was close to a Ryzen 7 3700X.
Including a case, PSU, a 500GB SSD, and a case, a computer that would *theoretically* match the Xbox Series X in performance would cost approximately $1200. [Here’s what I chose, if you’re curious.](https://pcpartpicker.com/list/2QWmVw)
