Wasnt sure if you guys read this, but looks like the DX12 put the AMD 290x ahead of the titan x and 33% more gains then the 980GTX, I love my lightning 290x :)
 
DX12 support has just been added to 3DMark showing unbelievable results with DX12 delivering up to 20 times faster performance than DX11. AMD Radeon graphics cards are showing the most significant gains compared to their Nvidia GeForce GTX counterparts. 



Testing has shown in fact that with AMD’s most recent driver update the R9 290X is not only on par with the $999 12GB GeForce GTX Titan X, but also maintains a minute edge against the Nvidia flagship. When compared against Nvidia’s $549 GTX 980 the R9 290X from AMD delivered a 33% performance lead.

AMD, Nvidia, DirectX 12, DX12 
Testing has shown in fact that with AMD’s most recent driver update the R9 290X is not only on par with the $999 12GB GeForce GTX Titan X, but also maintains a minute edge against the Nvidia flagship. When compared against Nvidia’s $549 GTX 980 the R9 290X from AMD delivered a 33% performance lead. 
AMD R9 290X As Fast As Titan X in DX12 Enabled 3DMark – 33% Faster Than GTX 980 
Results from both PCWorld and PCPer are in. 
dx12-980dx12_api_perf_mantle-100575202-origdx12_api_perf_4770k_titanx-100575302-origdx12-290xdx12-980dx12_api_perf_mantle-100575202-orig 

PCWorld’s results show the difference in API draw call handling between both the Nvidia GeForce GTX Titan X and the AMD Radeon R9 290X. With DX11 the Titan X manages a maximum of 740 thousand drawcalls per second and a whopping 13 million, 419 thousand calls with DX12. In comparison the 290X manages a maximum of 935 thousand drawcalls with DX11, so more than the Titan X to begin with and again an unbelievable 13 million, 474 thousand calls with DX12. So the 290X slightly edges out the Titan X in DX12 drawcall handling.Interestingly enough AMD’s latest drivers have improved DX12 performance to the point where it’s actually a head of Mantle by about 8%. 
PCPer’s testing is more traditional, showing the frames per second instead of the number of drawcalls per second. The GTX 980 delivers 15.67 FPS in DX12, a massive improvement compared to the 2.75 FPS it manages in DX11. On the other hand AMD’s R9 290X delivers 19.12 frames per second in DX12 a significant jump over the GTX 980. And perhaps what’s more interesting is that the next iteration of 3DMark which will debut with Windows 10 also supports Mantle. And the 290X delivers 20.88 FPS in the same benchmark running Mantle. A 33% performance lead over the GTX 980 running DX11 and a 9% lead over the same 290X running DX11. 
Last but not least, let’s take a quick look at the performance scaling in relation to the number of CPU cores. DX12 shows remarkable scaling with the addition of more CPU cores but hits a wall at 6 cores. On the other hand Mantle will continue to scale beyond 6 cores, showing extended performance scaling over DX12 with eight cores. I should point out an interesting phenomenon that occurs when hyperthreading is enabled with eight cores for a total of 16 threads. it seems that neither the GTX 980 from Nvidia or the R9 290X from AMD will make use of Intel’s hyperthreading technology. In fact performance shows slight degradation with HT on vs off with the R9 290X. 


I should remind everyone that these are synthetic benchmarks which should not be taken as the be-all end-all performance metric. Also please keep in mind that the race for faster, more efficient DX12 drivers is still in its infancy and very much represents a leapfrog pattern at this point. Last time we reported on the state of DX12 drivers and performance Nvidia was ahead. Today we see the roles being reversed with AMD taking the lead. However I’m more interested in testing out actual DX12 games when they come out. Which is rumored to be around the end of the year. In the meantime stay tuned as we may have our own DX12 3DMark results to present soon ! 
UPDATE : 
I thought I might as well delve into a peculiar phenomenon that PCPer.com had run into in their testing. Which is that once the DX12 benchmark was run on the lower tier GPUs after they were overclocked the result was actually far closer to their higher end siblings than would’ve made sense. Futuremark did not provide an explanation nor did PCPer attempt to do so. 


However what would explain this phenomenon is that the amount of drawcalls that the GPU can handle aren’t necessarily tied to the amount of shaders available on the GPU. Because remember the DX12 3DMark test in question only involves polygons and textures, no shaders. What would determine how many drawcalls the chip can handle comes down to software and hardware. 
Note how the 960 and 980 show identical numbers in DX11, while the 290X and 285 also show identical numbers in DX11. So this explains the software part. Once we remove the API software bottleneck we expose another bottleneck or in this case probably multiple other bottlenecks. In this case It’s most likely due to the amount of available bandwidth to the GPU in addition to the internal GPU hardware and semantics by which CPU drawcalls are handled. 
So what could explain the relatively small delta between the R9 285 and the 290X is that the 285 has eight asynchronous compute engines, exactly the same as the 290X. These are engines built directly into the GPU core itself which are responsible for handing out tasks to the various compute units / shaders inside the chip. However the additional memory bandwidth which the R9 290X has available to it compared to the 285 could be the reason why it can still edge out the 285 . In the case of the GTX 960, the result doesn’t make much sense either. Because the GPU was overclocked by approximately 30% yet that resulted in the GPU handling 57% more drawcalls. 
All in all as mentioned previously, synthetic benchmarks are very rarely the ideal metric to reflect real world performance. So the numbers you see above should only be taken as a rough estimate of how much superior lower level APIs such as DX12 and Mantle are compared to established traditional approaches which is what DX11 represents today.

    So you're saying that it's a waste of $$$ and effort trying to get our GTX 980s when that R9 290X for the price of a GTX 970 was going to blow it away?  Whew...  /me smells fanboyism here.

    This will change multiple times. No one knows until there is actual DX12 code in the games. Still got a ways to go until that gets done.

    LOL! I love EVGA! But for there PSU and MOtherboards. Yes I'm a AMD GPU fanboy, sorry :( I have tried all models even the 980 gtx and just was not impressed with the performance for the $$.

    Well, I have an EVGA PSU, and I've been big on EVGA's GPUs since the 6600GT.  For motherboards, I've always been either ASUS or Gigabyte.  The only time I've ever had AMD was the HD5850 from Sapphire, and a few of their CPUs over the years.  Other than that, I've always thought of EVGA and nVidia before much else.

    I just don't get it. I don't try to tell AMD video card users in there forums my card is better then yours. Does this make them feel better? Or fill that deep lost feeling. I am not sure. Not once have I ever wished I got an AMD video card. The only time I remember that there is one its like they hurry to say see before its too late. What ever. Good luck AMD wont care when DX12 hits I have plenty of EVGA cards to fill up every slot on my boards. 3 760s sli and 780 6gb px  5000plus cudas all at once I think I will be ok thanks.
     
     
    updated ok found it under features in 3dmark never would have seen it.

    yes I just tried it dx12 still not hitting it right. but the dx 11 sure does. Just a bunch of buildings like in bleach movie 4 when he is in hell. No effort in creation on then makers side as usual. and nothing to compare it to.  Score was valid using the like 50000 frames with 1,500,000 renders with the EVGA GTX 780 6GB SC

    970 Reigns supreme versus the 290x price, performance, wattage, heat...... even on uber mode.. and you come here complaining that AMD is better @ DX12 than nvidia???

    Are we even reading the same info? The data out on DX12 showed that AMD Was very far behind nVidia because of the fact AMD had Mantle, even tho even that did worse. Take you're fanboy crap elsewhere. AMD has even abandoned Mantle due to DX12...
