When do the next generation GPUs drop?


#1483

The 1070gtx is working well for me, and I will definitely grab the 1080 equivalent when the Volta cards ship.


#1484

Looking at Newegg I am glad I got my 1060 6gb card for what I felt was a ripoff 270 bucks. Sheesh


#1485

Also early reports are that it only generates 30MH/sec, around the same as a GTX1070. Given its power consumption, it’s a terrible coin miner. Could be broken drivers, still very early.

#1486

Yes indeed, same here Scott.


#1487

The rumors about it being great for mining were started by a vendor trying to pump up preorders. They never made a lot sense; why would Vega RX be any good when the Vega FE wasn’t? The 100MH/s number was particularly unbelievable. Vega doesn’t have anywhere near enough memory bandwidth for that, the absolute theoretical maximum is about 60MH/s. And nothing ever reaches the theoretical max.

It’ll be interesting to find out exactly what went wrong. Because it’s not just that they had to pump up the voltages to reach their target clock speeds. It’s pretty miserable on other metrics too. What are they doing with all that silicon? There were supposed to be half a dozen major new architectural features; why are none of them making any difference? Why the long delay between FE and RX Vega? It clearly wasn’t about finishing the “magic drivers”.


#1488

The reason why it might still be good for mining is because it has fp8 and fp16 support, although it would require rewriting the miners.


#1489

You can’t rewrite the underlying hash functions using floating point. The core operations are mostly bit operations, e.g. XORs, ANDs, rotates. Low accuracy floating point will be great for machine learning though.


#1490

It seems that with GPUs AMD hasn’t been competitive (performance, power efficiency, PCB length) since the 6xxx or 7xxx series?


#1491

The Fury Nano competed on PCB length, and the RX-480 was very competitive on price.


#1492

No SR-IOV on consumer Vega either.

It’s really strange, with CPUs AMD finally understood that they shouldn’t play these silly artificial market segmentation games. But in GPUs where you’d think they could use any possible advantage? Nope.


#1493

They’ve added mining specific instructions to the ISA in Vega. To soon to know how those will pan out.


#1494

The correct answer is to get the card to decrypt its own BIOS. Go, math!

Meanwhile, can someone tell me that my 7870XT is still good for games? I just want to not always browse the video cards page of online stores…it’s a bad habit…


#1495

7870 should be OK for 1080p gaming. Not 60fps and not maxed settings, but generally OK. It’s a bit faster than the release PS4 and Xbone GPUs. You can stretch it out another year or two if required.


#1496

I’ve had the same habit lately, and it’s a depressing one. You know things are bad when I check every day, hoping against hope, trying to find a sale where I can get a 1080 for the low low price of . . . MSRP.


#1497

I’m selling my old 980ti if you wanna upgrade, Kao.


#1498

It’s up to 36 vs 32 for a 1080 Ti with first driver tweaks. If it gets another 10 or 15 percent it might be a real problem for anyone buying it for games again.


#1499

Hey let’s put out a driver specifically for miners so any gamers that want Vega are SOL


#1500

Based on the power utilization and heat generation, there’s no particular reason for gamers to buy Vega anyway, unless they have a freesync monitor. If it excels at coin mining at least AMD can sell their product.


#1501

Are there people that buy high end GPUs but refuse to buy a G-Sync or Freesync monitor?


#1502

Not exactly refuse, but the lower cost of a Vega+FreeSync package over a 1070 or 1080+Gsync package is probably going to tip the decision for me. I have power to spare and don’t really care about heat.
