This isn't the same model or even type of IC, though. Each IC has a different cost, so it's an apples to oranges comparison. Sure using standard ~16-18Gbps GDDR6 is cheaper, but Nvidia's cards have that specific bin, and chip type of GDDR6X that I referred to in the Digikey argument. You can double check with W1zzard's reviews.
I've not forgotten any of this.
1. No, RX 5700 XT cannot do raytracing at all. It's just not compatible with the technology and AMD has made absolutely no effort to support a software DXR driver on this hardware. This was their choice. The RTX 2080 may lack the performance of its higher end and contemporary siblings, but it is fully compatible with DirectX 12 Ultimate. AMD has no claim to this prior to RDNA 2.
2. Regardless of die size and cost, the TU104 served as Turing's midrange offering alongside the low-end TU106 and the high-end TU102. Its larger die area is owed to the earlier fabrication process and the presence of extra hardware features that the competition plain didn't support. We know Turing was expensive, but it's the one thing you're completely unwilling to accept: reality is that midrange GPUs have been costing $800 for some time now. And that's not about to change. The way the market is going - and this includes AMD, is that the pricing "floor" on cards that are worth buying is consistently being raised generation after generation. There's an interesting video that's been making the rounds recently where the guy approaches exactly this problem:
3. Regarding FP64, frankly, who cares? The ratio may have changed to more or less keep this about the same level but FP64 is increasingly unimportant across all kinds of GPU computing segments. Has been for many years, remember 10 years ago when Titan X Maxwell removed the FP64 dedicated cores that the Kepler models had? It's not that they were disabled, Maxwell simply didn't support that... there was no demand for that then, and there is no demand for it now. Titan optimizations went beyond FP64, they simply enabled the optimizations from their enterprise drivers for targeted applications such as specviewperf and similar suites in an answer to AMD's Vega Frontier Edition semi-pro GPU. I owned one and AMD abandoned it, feature incomplete, far before announcing GCN5 EOL because they simply did not care for maintaining that product and the promise they had made to its buyers.
4. Neither the PS5 nor the Xbox Series are particularly powerful in comparison to a contemporary PC. Digital Foundry's placed an RTX 4080 SUPER at about ~3-3.2x the performance of a PS5. The PS5 may have a few tricks up its sleeve like the aforementioned dedicated decomp engine but... on the other hand, we've got far more powerful processors with much faster storage and much faster memory available, so really, it balances that out even if you disregard things like DirectStorage.
The "intentionally making their products obsolete sooner" argument flies directly in the face of Nvidia's lengthy and comprehensive software support over the years. I'd argue nothing makes a graphics card more obsolete than ceasing its driver support, and AMD has already axed pretty much everything older than the RX 5700 XT already.
It's not some big scheme, they just upmarked the SKUs in relation to the processor that powered them way too much. AMD did the same, and why you ended with such a massive gap between the 7600 (full Navi 33) and the 7800 XT (full Navi 32). They had to shoehorn SKUs between these, and it resulted in a crippled 7700 XT that's got 12 GB of VRAM and became unpopular because of it, and a 7600 XT that's basically a 16 GB 7600 that... no one sane would purchase at the prices being asked, and was received just as poorly as the 16 GB 4060 Ti.
For $100 you're taking:
- NVIDIA's vastly superior software ecosystem (all the bells and whistles) with a much longer support lifecycle
- Identical raster with 20% extra RT performance
- A GPU with a higher power efficiency figure
That's very much up to you... personally, I wouldn't touch the XTX if I was asked to choose between it at $900 and the 4080S at $1K. The XTX needs to be priced at $799 to become a clear winner in my eyes.
