Battlefield 4
“Battlefield 4 is coming to PC, powered by the advanced technology of DICE’s proprietary Frostbite 3 engine. Blur the line between game and glory in Battlefield 4. With dynamic destructable environments, vehicular combat, and the chaos of all-out-war with 64 players, Battlefield 4 on PC will be an unmatched interactive experience. In addition to its hallmark multiplayer, Battlefield 4 features an intense, dramatic character-driven campaign that starts with the evacuation of American VIPs from Shanghai and follows your squad’s struggle to find its way home. There is no comparison. Immerse yourself in the glorious chaos of all-out war, found only in Battlefield.” From Battlefield.com
In Battlefield 4 we did a 5 minute loop of the test range, we tried to make the loops as repetitive as possible to keep things accurate but please consider Battlefield 4 has no official benchmark tool so there is more margin of error than usual. To record frame-rates in DX11 mode we used the Fraps benchmark tool, to record in Mantle mode we used Battlefield 4’s built in FPS counter. Sadly this doesn’t give minimum or maximum frame-rates, it is only possible to figure out the average. To start the frame rate tracking in Battlefield 4 you need to enter PerfOverlay.drawfps 1 into the console and then PerfOverlay.drawfps 0 to end frame tracking. You can also enter render.drawscreeninfo 1 into the console to double check which API is being used to render. Battlefield 4 outputs a csv file document into the Battlefield 4 MyGames folder which lists all the frames and the frame duration. From that list you can calculate the average frame rate. We used the Ultra preset without V-Sync at 1920 x 1080 to test.
As our results show the move from DX11 to Mantle made dramatic improvements for both CPUs. The FX 4100 and FX 8350 saw frame rate rises of around 12 FPS which is a very nice gain. The results suggest that even with the assistance of the Mantle API Battlefield 4 is still CPU limited. However, the results are hugely promising, the FX 4100 with Mantle performs the same as the FX 8350 with DX11!
How about with core i3 or Pentium Anniversary edition with mantle? i wonder how much gain they can get…
well you will get a small performance boost, but mantle is most efficent with AMD gear. I remember i saw some video (linustechtips) where they compared AMD some 4k or something APU series and a R9 2xx and some intel i7 i think it was with a r9 2xx and the AMD combo was significantly better
Yes its about overcoming CPU bottlenecks so AMD CPUs always gain the most as they always perform worse so there is more bottleneck to be removed by Mantle.
core i3 and pentium anniversary is intel low-mid end offering so i just wonder if the gain will be enough to close the gap against core i7. given im still running core i3-530, how much of gain is what im trying to find out but most review out there prefer to compare a10 apu and core i7…
Well we do not have either of those CPUs but we will expand testing to include the anniversary edition CPU when AMD add more Mantle games later on. I’d presume the pentium anniversary would make a 10-15% gain. On your i3 530 which is clarkdale and fairly old I’d say you’ll see similar gains to the FX 8350: 20-30%.
not likely. even with cpu bottleneck removed, AMD cpu’s are still behind by about 2 cores to 1 margin. I know AMD loves to pull the card that their competitor is doing things to make games run worse on their hardware. So could the test be setup to run worse on intel chips?
Without Intel CPUs this article is not so much. We all know AMD CPUs cause bottleneck. Lets see some amd and intel comp.
I agree, AMD cpu’s being slower per core means more likely to be the bottle neck using directx.
bottleneck my dick i can play BF3 on ultra @ 60fps on my 7850k
Also dont forget to test mantle with 2 gb amd vga card.
Huh, funny thing with theif test, my 4770k at stock clocks and a gtx780 avg’s almost 70fps using directx. Yet an 8350 + 290x using mantle is 15% slower. yes using very high settings as well.
