I haven't done Firestrike Ultra, but my 2080 does 31K in vanilla Firestrike. It has a conservative OC because this model is severely power limited in the BIOS. I could probably get 32K+ with a flash, seen as it doesn't break 50ºC.

If that 27K score is at stock, the VII will, indeed, match a 2080 when OC'd, which is great news.

What is this bs you keep spouting? Sure HBMII is expensive, but VegaII is not a huge die. About 1/3 smaller than RTX 2080. They will do just fine. You add in the fact 1080Ti performance will decrease as new drivers come out, and AMD's will increase.. and you have a clear winner AMD has in the under $1000 market. QFT.

Do we have proper specs? I head double the rops?

Any ideas when reviews go live?

It's a MI50 for consumers (cut down FP64 aka double precision). It's 64 ROPs so most of the gains are from clockspeed , the increased HBM2 throughput (higher at nearly 1TB/s instead of ~ 480 MB/s), and the 7nm as far as power efficiency.

~1500MHz on Vega 10 to ~1800MHz on Vega 20 7nm , which is ~20% but there's a reduction of CU from 64 to 60

It's been stated at 27% increase over Vega 64 per AMD, so just use that as a reference point.

Yes, we do have proper specs, it's a repurposed professional card, the 7nm Radeon Instinct MI50, but with a 1750 Mhz Boost and 1800 Mhz Peak clock and 1/8 FP64 performance (between an original Titan and Titan Black, which makes it an interesting compute card, but fortunately not good enough for non gamers to snatch them all up). The basic design is the same as Vega 64 and 56, so the ROP count is still at 64. There was some talk on the CES floor about it being 128, hence why initially some outlets reported it as having 128 ROPs, but AMD has already clarified that it's the same 64 ROPs as before.

The core count sits at 3840, so it's a bit harvested compared to the full chip. But as we know by now, the 4096 core design with 64 ROPs is bottlenecked, has been since the Fury X, so for gaming less cores active and higher clocks probably makes the most sense anyway.

Memory is 16 GB of HBM2 running at 2 Ghz effective on a 4096-bit bus for a massive 1 TB/s bandwidth. Technically speaking this is the first PCIe 4.0 chip, but AMD did not enable that part for the desktop Radeon VII, only the Instinct parts are PCIe 4.0. PCIe 3.0 should be more than enough for this card anyway.

TDP is not 100% certain, but it's probably the same 295w of Vega 64.

Thanks for that. Will see how it overclocks but seems a bit pricey for what it is. Probably because all the ram.

But your not taking into account how far behind it is in Timespy. 8700 vs a stock 2080's 10,000 plus. That's a massive difference.

AMD cards perform terribly on TimeSpy, gaming performance is completely different. I picked the highest two GPU scores with a 6700k, you'll notice the highest single Vega 64 score is mine with a 6700k haha

GTX 1080: https://www.3dmark.com/spy/4678738
RX Vega 64 LC: https://www.3dmark.com/spy/5013755

While FireStrike AMD performs amazingly at.

Not sure what rock you have been living under but basically all reports on cost for this card point to it having an extremely low, possibly negative, profit margin.

The die is smaller than the 2080, sure, but going to 7nm likely cost enough for the that size advantage to not matter in terms of cost per chip.

1080ti performance in traditional rendering scenarios will not decrease lol, and yes, maybe the v2 will increase a bit over time (though I am not sure how much more optimizing can be done since it is basically the exact same as vega 56/64). However; let's just pretend that 1080ti performance does decrease for argument sake... you are forgetting the RTX 2080, you know- the card that has been available since SEPTEMBER that is priced the exact same as the V2... the card that is already 5%< faster than the 1080ti??? It will consume less power than the V2, it will be anywhere from 5-15% faster in games on average over the V2, and has the OPTION to use RTX features that AMD currently has no answer for. How on EARTH do you declare the V2 a clear winner below $1000???????????

The funniest part is, the RTX 2080 might be one of the worst cards, in terms of value (outside of flagships), that has hit the market in years. The V2 managed to be even worse.

I think this is the first time ATi/AMD didn't release a card with DirectX's major feature compatibility. I agree with Jensen Huang with the Vega VII being underwhelming. All these DxR cards being releasing and we only have one choice of card. AMD didn't even release drivers for Vega for us to see just how terrible Ray Tracing would be on their cards.
