I'd rather spring for a 7800X3D. The 7900X3D fills a legitimate niche of wanting OK multicore performance, OK gaming performance, and a good price, but the problem is games are lassoed to the CCD with extra cache so for gaming, it runs like a...

A much needed rebranding. The precious metals based scheme was utter chaos, with at one point something like 100 finely segmented SKUs. Conroe to Haswell at least had feature parity across the entire stack (except for the two socket-filler SKUs...

1-2% performance for dumping an extra 200w of heat into your environment... No thanks! I think Nvidia has it right.

yes, by lowering the boost clock or increasing Vcore (which will reduce the boost duration), both of which have a negative impact on performance.

Tricky question. 5120x1440 is the same pixel count as 4K which means nothing other than a 4090 will be futureproof at maxed out settings. The 7900 XTX is a good contender, BUT DLSS is way better than FSR - DLSS uses game-specific learned...

While AMD does have a fair share of issues, the latest stability issues on the Intel side are not confidence inspiring, and furthermore, are obviously traceable to what is essentially a bad factory overclock, something which can't be patched in...

You're saying you want to upgrade and you want Intel, so I think you answered your own question - besides the 14700K and 14900K there aren't any other sensible choices for gaming on Intel right now. That being said, Ryzen 7000X3D is the gaming...

they were worth $3K a piece in china right before the sanctions kicked in so there was a ton of scalping. it looks like pricing has settled back down now

yes, but at what cost? at 3 tokens per second you might as well use a CPU. also, cifar-10 in resnet50 is not representative of AI workloads in 2024. the weights and activations are so small that it becomes difficult to achieve high arithmetic...

1660S/2060 have way too little VRAM to do anything meaningful. @OP the price of entry is $250, save up for a 3060 12GB or better yet, a 4060 TI 16 GB.

yeah 4090's are an incredibly good deal, you're looking at $500 for a yielded, tested, and packaged chip plus margins, then $100 of VRAM, plus PMICs, cooler, board, testing, packaging and distribution on the AIB side...AIB margins are not so good...

A 300mm wafer has a surface area of 70,000 sq mm, given the 4090 is 609mm2 the absolute best assuming 100% yield Nvidia can get there is 114 chips from that wafer. Given the current cost for TSMC is ~7000 for the wafer and another $20k to process...

Are you sure you don't want a...laptop? They run of off DC, are generally designed to have super low idle power, are built out of wide GPUs clocked low and binned for good low power performance, etc. If you were building a new rig you could get a...

I think its a design choice, not incompetence. AD102 has 30% more transistors than Navi 31, and performs about 30% faster. AMD's wafer starts are even more strained than Nvidia's - they have to fab Epyc, Ryzen, Navi, and Instinct, parts with...

The problem isn't profit, or margins, or whether Nvidia cares about you or not. The problem is foundry capacity. When you're not capacity-limited, you print as many chips as you can, then sell as many of those as high-margin enterprise parts as...
