Testing AMD’s Mantle
Plants vs Zombies: Garden Warfare
“Plants vs. Zombies Garden Warfare digs into the trenches with an explosive new Co-op and Multiplayer action experience. Blast zombies and plants across a mine-blowing world that delivers the depth of a traditional online shooter blended with the refreshing humor of Plants vs. Zombies.” From PvZGardenWarfare.com
In Plants Vs Zombies Garden Warfare we did a 5 minute loop of the Port Scallywag Map, we tried to make this as repetitive as possible to keep the results accurate. PvZ:GW does not have a benchmark tool so the margin of error is more significant than usual. We used Fraps to monitor the frame-rate during DX11 mode and during Mantle mode we had to use a make-shift frame-rate recording mechanism. Holding Ctrl+R gives a frame-rate counter in the top right of the screen. Using a custom screen-capture program I then captured a screenshot of the benchmark run with the frame-rate counter showing every second throughout the duration of the benchmark run and averaged those out, that’s an average of 300 screenshots. This is a method that is subject to a lot of margin of error but it was the best we could do given the fact we or our AMD representative did not know of any frame-rate recording instrument within the game. We used the Ultra preset and the 1920 x 1080 resolution to test.
The results in PvZ:GW were staggering. From DX11 to Mantle we saw a 50FPS rise with the FX 4100 and a 40FPS rise with the FX 8350. This is hugely promising and goes to show how effect Mantle is, remember PvZ:GW is a very new game too so the significant jump will probably be improved down the line with more patches and such.
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.
