The most interesting thing is the difference in latency between DDR4 and GDDR6. If you ever wonder why Desktops don't use GDDR6 as ram for the CPU... Well this is why... (Lower the better)

I already argued this point back almost 10 years ago... When the Xbox One and Playstation 4 got unveiled... That the Xbox One would hold a CPU advantage, not just because of clockrates, but because of DRAM latency between DDR3 (Xbox) and GDDR5 (PS4).

But if you are running integrated graphics and you are primarily GPU bound, than GDDR memory is definitely the way to go, even if it comes at the cost of the CPU.

As for the CPU performance, while it's single threaded is only slightly lower than 3800X, it's multi-threaded is only slightly ahead of the 1800X. Due to the low cache and high memory latency, it makes sense. With console optimization and added hardware decompression blocks and such, it's probably perform somewhere between Zen + and Zen 2. Suffices to say, the CPU won't be an issue for the consoles this gen. The dream would have been to pair that up with an Nvidia GPU but that would have probably added another $100 to the price so probably not worth it.

Yeah. Between the Zen+ and Zen2 is a good ballpark, depending on workload of course... Clockrates hold it back from competing with low-end Zen3 though.

The hardware decompression generally just offloads that specific task, something the PC doesn't need to do anyway on the same scale.

The PCI-E slot though is a real real bummer to what could have otherwise been a fantastic cheap ITX rig.

Quite interesting results. Tbh since these consoles are aiming at high resolutions with low/mid range GPU's.. A CPU that performs around a 2700X is good enough to not be a bottleneck. Like most games are pushing for higher resolutions like 1440P and above with low framerate caps. I.e. 30 FPS with highest settings and 60FPS for performance. At which point these consoles are mostly GPU bound.

Kinda wished both made GPU's larger but that would have increased cost so it is what it is. A Nvidia GPU would have been great but it would have added extra complexity in design, materials and cost. But yeah Nvidia already burned the bridges with Sony and MS before on earlier consoles, so another colab is very unlikely to ever happen again which is unfortunate xP

Keep in mind that games/game engines are still built with Jaguar as the lowest common denominator in mind... Once we switch over to the 9th gen hardware completely, things might start to change and older PC's with old Quadcores+HT will start to feel far more limited than they already are.

Microsoft's GPU in the Series X is fairly large as-is, it sits between the 6700XT and 6800 GPU's in terms of functional units, it just lacks the clockrate to really push things to crazy heights to fit in a defined TDP envelope.
They did have to give up some die-space to accommodate the more capable CPU in the end... Console hardware is generally a balancing act.

Sadly AMD RDNA2 Ray Tracing is hot garbage (Speaking from experience here), so hopefully there is a revision/Pro console in a few years.
