That's impressive, looks like we could have a decade of decent competition and choice.

Hopefully it continues. I'm sure it won't happen but if they spend a lot of money on R+D and don't get payback from it, it's often one of the things to get trimmed first, unfortunately. It won't with Lisa at the helm but things can change.

Believe Nvidia's R+D is $740m a quarter, AMD's is now $442m, from $271m during Ryzen 1. AMD paying off their GF/ATI debts as well will give them more wiggle room to invest hopefully.

I get the impression AMD is driven by engineers rather than marketeers. More investment in R&D is what's needed, which is hopefully happening now.

I can't see Threadripper ever seeing the light of day in any other company. AMD have also pushed a lot of new technology, sometimes too early and to their detriment, but I think people like the ethos of "Build it because we can".

From memory i belive thread ripper wasn't in the orginal spec. Some engineers decided to build it in their spare time.

Exactly, only a company with a more engineer focused ethos would allow a part time project to reach retail. Especially when it had the potential to eat into other sales. Intel would never have sanctioned that. Their HEDT line up was expensive and even restricted PCIE lanes and RAID unless you dug deep and paid a significant amount extra.

I find it funny this "nvidia killer" name is sticking like there's any truth behind it. Clickbait at best for tech sites.

I hate the title of this thread, it might be a good GPU, a really good GPU, but its never going to be an "Nvidia killer"

FFS ridiculous exaggerations just build unrealistic expectations... I think AMD will make a good competitive GPU, but they are not Killing Nvidia!

I think most people mean it will kill Nvidia on price to performance rather than actually being faster. If Big Navi can match 2080ti performance and has Ray Tracing built in for £700 or so most people will be over the moon and Nvidia will be ‘dead’ or at least promoted into a proper refresh which maximises performance, not just the usual 20% faster but also 20% more expensive shtick they’ve been trotting out for years.

Think one of the recent news sites mentioned the phrase was in reference to Navi 23. ie the smallest and cheapest of the 3 and not the 'big' one (21).

Turing is not what AMD should be concerning themselves with, and i doubt they are, AMD's target is Ampre.

5700XT:

40 CU's (2560 Shaders) at ~1.9Ghz
64 ROP's
256Bit IMC
7nm 251mm ^2

Navi 21, 7nm+? 505mm 2^ theoretical:

80 CU's (5120 Shaders) at 2.2Ghz? PS5 RDNA2 GPU is 2.2Ghz.
ROP's?
IMC?


Navi 21 needs to gain 43% performance over the 5700XT to match the 2080TI, an 80 CU Navi 21 will do that, it will do a solid chunk more than that, No question Navi 21 will be significantly faster than the 2080TI, but how fast is Ampre?

Now that i actually have some experience with RDNA1 i'll add to it.

Power consumption on the 5700XT is all over the place between different vendors with the same reviewers. They range from 180 Watts to 220 Watts. Mine from personal experience is 200 Watt's out of the box, reviews that i have seen show the same thing, 200 Watts.

I have fiddled with mine, increased the actual running clock speeds from 1.9Ghz to 2Ghz and brought the power consumption down from 200 to 160 Watts, if AMD binned these GPU's keeping the better Silicone for the 5700XT's they wouldn't need 1.2v, that's WAY over what mine needs, which is 100% stable at 1.035v.

The fact that RDNA2 is in consoles with 2300 Shaders at 2.2Ghz in the case of the PS5 and 3300 Shaders at 1.9Ghz in the new XBox indicates AMD have improved the power consumption significantly RDNA2 vs RDNA1, the shaders despite the deflated mediocre view people have about RDNA1 are actually very efficient, compared to my 1920 Shader GTX 1070 at the same clock speed my 5700XT is anything from 50 to 70% faster and the 1070 used more power.

I have built a high tessellation map in Cryengine 5 to put AMD's historic weakness to the test, it humiliates the 1070 in that test.

Navi (RDNA1) is much better than people think it is, yet again people just had too higher expectations expecting it to crush a 1080TI and it didn't, the 1080TI has near 4000 Shaders and a 384Bit IMC, the 5700XT is small GPU punching way above its wight class. its a good GPU.

Don't expect an 80 CU RDNA2 GPU to beat a massive Ampre, but it will be a good GPU in its own right. :)

Same as vega really, totally over the top voltage that is unnecessary. You would think amd would be more conservative with voltages considering they're trying to get away from this "power hog" stigma that some of their gpu's have.

Yeah its frustrating, i don't get it, tweaking the volts results in 'significant' power draw reductions.
 
It will be an Nvidia killer though, just like as usual it will kill Nvidia’s then previous generation :p

Unless AMD price their cards super competitively like they used to in the past, it will just be meh again imo.

I’m concerned about production limits. Sony and MS will want a million units or more, potentially each so that really doesn’t leave much spare capacity for any PC Card. Availability is going to be very, very sketchy for a while I reckon. Which inevitably leads to price gouging. It be surprised if any retailer has hundreds of each AIB partner cards and those that do have stock will be marking up by ten, twenty or even forty percent. Because they can.

Agreed,and AMD has more ground to catchup than Nvidia,ie,not only power effiency,also RT performance,etc.

What we all want is solidly performing AMD GPUs,at a reasonably price. Releases such as the HD4870 or even HD5870 didn't beat Nvidia,but they were good GPUs.
