Man, I'm glad I snuck a 1080ti purchase in a few years ago when BTC was crashing hard. Of course, being Nvidia means it'll suck if I have to transition to a Linux Desktop before the next cryptoshit market crash, but if it takes that long then they've probably managed to kill of high-end PC gaming along with the environment and I'll have bigger problems.

The fact that the entry-level card can run its clock 30% faster than the same line's top-end offering supports the story pretty solidly, IMO. Not supporting 8 GB of vram can't have given them enough breathing room to casually run the clock that fast, so this has to have been decided way up front.

The RX 6500 XT is a worse card than the RX480 released 5 years ago https://i.redd.it/oyxyoxmch2a81.jpg .

I'd expect otherwise actually.

RDNA is far more efficient at gaming. GCN was compute-focused (higher TFLOPs, but weaker in practice). Case in point, micro-benchmarks show that VRAM latency is ~100 nanoseconds on RDNA, but ~300 nanoseconds on GCN.

RX 6500 XT is aimed at roughly the same specs as the RX480, but should perform slightly faster in practice, along with Raytracing support, Infinity Cache and therefore faster VRAM latency (probably faster fill-rates and other microbenchmarks important to gaming), all at 107W instead of 150W.

---------

As such, Rx 480 would be a better mining card, while 6500 XT would be a worse mining card, but better video game card.

Its still stupid for AMD to market their cards like this, but they're not lying... (and whatever argument marketing wants to make... well... that's their job. It all looks stupid to me but I can't honestly call them out on it since it is true...)

-------

Turns out that video-gamers who want more uniformity and less jitter between frames want higher-clock speeds (notice the 2000+ MHz clock speed on 6500 XT) rather than raw TFLOPs (Rx 480 ran a slow clock of ~1000MHz but had many more compute units / SIMD units computing in parallel).

Width of GPU leads to more variance, because its harder to load-balance your parallelism. If you have a narrower GPU (fewer compute units) at higher speeds, its easier to reach more consistent frame times / less jitter.

fwiw I've used nvidia drivers through DKMS for a long time and never really had any issues with it.

Good way to spin having only 4GB vram into an 'anti-mining feature' I guess. Of course, 4GB is typically considered the bare minimum for modern 1080p (let alone higher) gaming and this is just a budget card which was definitely not limited with any mining considerations.

The fact that the entry-level card can run its clock 30% faster than the same line's top-end offering supports the story pretty solidly, IMO. Not supporting 8 GB of vram can't have given them enough breathing room to casually run the clock that fast, so this has to have been decided way up front.

I'm afraid it isn't worth much, considering how many times a Linux Desktop user has told me "I haven't really had any problems with it" about something that ended up giving me no end of problems.

Ethereum price crashing is what let you buy it. You might thinking the wrong decade but then the 1080ti didn't exist, and neither did Ethereum.

World really needs a ban on PoW cryptocurrencies. I guess on one side lot of people is not caring about it as long as they make some money of it, and in the other side maybe other people in power, is not caring as that would make a perfect excuse to ban any kind of cryptocurrency. I guess too we all will care as soon as the devastation caused by the climate change becomes a massive life threatening issue.

That picture is misleading. It doesn't show that the 6500 has >2x the clock speed and lower power requirements.

2x the clock speed is crazy.

I don't think that's true - the GTX 1060, which was its' competitor, and matched it's performance pretty closely only had 4.375 TFLOPS of compute. Architecture matters
