It is a relatively easy gain compared to arch gains and you don't need to shrink to get it.

The main win is the cpu side though.

AMD introduces mantle-systems with radeons see gains. Nvidia bites and supports mantle in some form. Game developers start to use mantle massively, now that both vendors support it. AMD proceeds to tweak mantle so it always runs better in radeons.

Nvidia will fight mantle to the bitter end.

Let them. If that's NVidia's attitude and culture, they don't deserve to be in the market in this day and age. NVidia wants a proprietary, locked in, all nvidia future with no regard to gamers. Gamers come second, or rather third of fourth. I'll still have CPU boundless Mantle goodness regardless of what nvidia does so what they decide to do is irrelevant to me.

Radeon 290x using Mantle: 65.7 fps
Radeon 290x using DirectX: 55.4

Overall 19% faster at this configuration

19 percent is nothing to scoff at plus it will get better overtime :O

It's not like Mantle would be this thing that only AMD could tweak and improve. I don't think the main competition here is Nvidia vs AMD, but rather Mantle vs DX.

We know more than anything Mantle is about reducing CPU overhead and improving efficiency in the rendering pipeline. Anything that gives AMD's low-mid tier CPUs a boost is a win for them since it means more people can game using cheaper AMD CPUs instead of costly Intel ones.

I'm sure AMD wont mind people buying their CPUs even if it means they purchase a shiny new Nvidia GPU. The real enemy here is Microsoft with their bloaty API and Intel with their CPU performance. The real gain here would be tweaking performance of Mantle to work better with AMD CPUs instead of Intel CPUs.

Nvidia working with AMD would help make that reality much faster than AMD on their own.

If they do what they claim they would it will be an open standards api so each vendor would have their own driver implementation and the above wouldn't really be possible.

Its probably more in AMDs interest to get NVidia on board than not, as the way i see it HSA adoption is the long term goal here moreso than selling a few extra gpus.

Siege of Shanghai with 64 players


System Specs
64 players, Ultra Details (Core i7 3770K, 16 GB DDR3-1333, Radeon R9 290X@1.000 / 2500 MHz, Windows 8.1 x64, Catalyst 14.1 Beta)

To measure the multi-player mode, costs especially time - despite the used SSD for OS and Battlefield 4: The map and all the 60 + players must be loaded (we measure on always the same server with at least 60 players) and the Spawn needs to an appropriate Agent. This makes it not fail, we are playing on the map "Siege of Shanghai" on the part of Americans and grab us in their basic personal watercraft.

Warning: Spoiler! (Click to show)

Our test scene: a jetski ride across the BF4-Map Siege of Shanghai
Quote:
With this we go to the flag point A passing along the promenade, swing on the third pier to the right in the direction flag point C and continue on the intact skyscrapers passing under the bridge between the flag points C and D. Because of the battle around us explodes sporadically a tank or a helicopter roars past - therefore we submit five passages in order to obtain a representative FPS value and leave passages that vary widely, outside before.


High performance gains in CPU limit

Quote:
In the graphics limit the 4K resolution (3,840 x 2,160 pixels) overloaded the Mantle API the Radeon R9 290X little better, the average frame rate increases by 7 percent. In common with many players 1080p resolution (without MSAA) our test scene is already almost continuously CPU limited, the frame rate under Mantle is, therefore, a whopping 76 percent higher than in Direct3D - with 4x MSAA, there are still up 35 percent.

Are most marked differences at a resolution of 1280 x 720 pixels: Video card must be here throughout on data from the processor to wait, so the speed is increased by 78 percent. Particularly noteworthy is the minimum frame rate, which is significantly higher among Mantle as under Direct3D. This also means that users of Crossfire and 120-Hz screens, the Radeon-teams have been limited by the CPU, its performance can now take full advantage.

The frametimes also demonstrate that the images are output not only faster but also more evenly. In the same nominal frame rate is thus the feel somewhat improved. Particularly impressive are the values ​​taking account of Windows 8.1 and Direct3D 11.1, since 7 and D3D11.0 benefited Battlefield 4 of both compared to Windows.

YES! Death to Nvidia! Monopoly time!!!!!! So much innovation comes from a monopolized market! Just look @ Cable speeds in America since comcast basically monopolized the nation!

If they can just translate the 720P gains into the UHD resolutions the world will be golden, though that's unlikely.

yet another broken review. Who would Dumb enough to put just a 3570K with a low-mid end 260X?

3570K is for GPU like 280X. Check people sig for spec, most 3570K gamer have GPU faster than 260X

No minimum frames either, wonder if mantle is smoother regardless of average frames
