mantle in a nutshell is AMD's initiative to create a new programming model to
fully exploit the capabilities of modern gpus to improve graphics performance
that's directly from their
literature The Cooler Master glacer 240l CPU Cooler delivers the convenience of
an all-in-one and the performance of a custom water cooler click now to learn
more the idea is to give developers the ability to have their game and interact
directly with the hardware to reduce unnecessary overhead to take advantage
of mantle right now you'll need a gcn architecture AMD Radeon graphics card
with a mantle compatible driver and a mantle ready game at the moment the only
game commercially available is Battlefield 4 but AMD also has a
benchmark called star swarm that was built using the oxide engine that you
can download on Steam now performance with mantle is a bit of a complicated
story it is supposed to improve performance but it's not that simple so
I'm going to hand the video over to Luke who has spent the better part of a week
testing multiple CPU platforms multiple
graphics cards multiple benchmarking segments within Battlefield 4 and
generally going on a voyage of discovery about this exciting new technology from
AMD without further Ado I'll let him take it away the original purpose of
this video was actually to go on the steam Hardware survey and figure out
what a lot of people were running and we were then going to Benchmark those cards
and those setups to figure out what tangible benefit people would get now
with mantle that didn't really work out so well and I'll get into that more
later on but for now we'll go into what actually we ended up doing to actually
get the results that we were hoping to I changed from storming the beach on the Singapore level like I normally do with
Battlefield 4 benchmarks and went to the broken Flight Deck this is a little bit
more CPU intensive than the Singapore level is and a better representation of
mantle and we're trying to find better representations of of mantle in
Battlefield 4 so it kind of made sense uh the 3960x 290x platform that I was
running for this performed quite well and with the direct X11 to mantle
comparison when both of them were overclocked we got about a 133%
Improvement going to mantle that's very solid for just switching a settings in
your video settings uh but when we tried something that a few people have been
trying which is underclocking their CPU to see what kind of performance gains
they'll get then we moved the 3960x to 2 GHz and saw a 20% of which is a lot more
solid although I don't see this being that tangible because the availability
of really high-end powerful CPUs these days is making it so that not that many
people actually have weak CPUs the the price per performance of CPUs is quite
solid so most people even in the budget end are coming out with pretty solid
CPUs far above the 2 GHz range that I set that CPU to so back to the steam
Hardware survey I ran a ton of different stuff based on the information that we
got from the steam Hardware server so that went from radon 777s to 7850 to
797s to r9290 x's and then with CPUs we
went from 3960x to 4670 K to cavar CPUs
I had tons of different setups and mixes and stuff going on and that felt as
random and ridiculous as the results I got from those setups which didn't make
a ton of sense now I don't know where to throw blame at for this there's a fairly
new patch from EA for Battlefield there's a new beta driver from AMD
there's me testing on different levels in Battlefield there's fraps and the
built-in tool in Battlefield recording the FPS there's tons of different stuff
going on but either way these results were not properly representative of the
platform and I know that for sure because there are certain setups that
should have no matter what been above certain ones that they were not so these
numbers were not valid and I'm not showing them and hopefully if you're
watching this in the future all of those things have been resolved and that's why
I'm not showing them is because if you watch in the future and I show all these
problems and they're fixed then it's not very well applicable another thing to
note if you're running these benchmarks on your own the best results are shown
on gcn 1.1 that is the 290 series The
260 series and the 7790 uh if you are running on gcn 1.0
that's say the 7,000 series graphics cards uh you Mantle still works fine
you'll still still see improvements in especially the very specialized situations like starstorm which we'll
talk about later but it won't be quite as nice as the improvements you'll see
on gcn 1.1 another thing to note might be that Battlefield 4 isn't actually in
my opinion the best representation of mantle to really show mantle off you
need a lot more CPU horsepower under there pushing the CPU as hard as you
possibly can and with that enter star
swarm star swarm is an entirely another Beast this thing will punish your CPU as
much as it possibly can and that's perfect to show off mantle so we tried
this out in a ton of different ways and you can see in every different way I
tried it out the simple switch over to mantle just completely destroyed it in a
way that is speaks more than just the
numbers this can actually unlock different types of games people can
start developing things for manle that they weren't able to develop before
maybe it's still an RTS but it's on a completely different level because each
individual guy can have their own very highly Advanced Ai and you can have
thousands of these little individual guys imagine playing an RTS with there's
some of them out there but with thousands of little minions but having them all be very Advanced AI That's
something interesting to think about we even have games coming up in the near
future that are already planned that can take huge advantage of mantle like Star
Citizen there's going to be huge amounts of ships in one small area with AI
controlled turrets with AI Manning different systems within your ship that
is in this giant system and it's going to be nuts there's projectiles going to
be flying all over the place and mantle will definitely help there as always

place for total members and we're getting close to Second so be sure to
join and just are you excited for this
type of thing are you excited for mantle are you excited for the games that will
be able to come out with mantel are you excited for the performance that mantle
can unlock for you comment down below as always like and dislike the video
