I don't see where it says that...?
"About half an hour ago, AMD sent us the drivers for our own performance evaluations."
Looks like we will be getting mantle tomorrow

I wonder if these trolls are being paid, I don't know why anyone would spend so much time talking about something that they aren't interested in.
I have typed this same response to this backwards compatibility nonsense and no one ever responds. Please tell me why mantle needs to be backwards compatible?
AMD cards are not dropping support for direct x. They are backwards compatible. This is honestly the worst thought out fud in a thread full of fud. The important thing for AMD and Mantle is going to be forward compatibility not backwards.
Mantle will do nothing to change the performance of older titles where AMD has performance parity across price ranges with nvidia already because they support direct x and will continue to. Just stop posting about backwards compatibility. It has no place in this debate because it is a non issue.
I will post whatever I feel like, thank you, unless the mods tell me it is inappropriate. As to why it needs to be backwards compatible, the answer is obvious: because to become a truly wide ranging API it needs to be able to provide improved performance to *all* games, not just a select few on certain hardware, under certain settings. As long as that is all it can do it is a very limited benefit. It can be a "non-issue" to you if you want it to be, but it certainly isnt to me.

Mantle surely isn't backwards compatible for 7xxx owners because AMD already stated gcn 1.0 showed degraded performance and it will be addressed later. So, tell me about backwards compatibility again?
If Mantle can gain major performance improvements by being multi-threaded, then CPU's can make rapid improvements in the same way that GPU's have, by adding more cores. The problem is, many CPU tasks are not well suited to parallel processing. Mantle does give a way for the CPU to keep up, though it would be best if all games started doing this. Getting DX to do similar things would go a long ways to giving CPU's a way to improve speeds much like GPU's do.I think what's being missed is that mantle addresses the fact that CPU performance has stagnated, especially in comparison to GPU performance. GPUs are 100-150% faster than they were 3-4 years ago, while CPUs are only 10-20% better max. And AMD has given up on the high end CPUs, while Intel is pretty much doing the same by focusing on power saving and on board GPUs, which no one cares about on high end.
Mantle plays right into this.

And you won't buy a CGN card, and continue to be very happy without Mantle. I got no problem with that. I am interested in the possibilities of Mantle, and apparently a few others range from curious to interested to excited to starry-eyed. I have no problem with whatever anyone wants to believe. FWIW... I am somewhere between interested and excited.As long as that is all it can do it is a very limited benefit. It can be a "non-issue" to you if you want it to be, but it certainly isnt to me.
Reads like a philanthropist mission statement. I dont think any company who developes technology and hardware is not thinking the same thing, move the industry forward. I do think that a lot of it has to do with offering an incentive to purchase a product first and to be a savior second.
It is interesting how the narrative from Mantle went from outrageous performance gains from 1000000 draw calls
So I am reading another new online story about Mantle which references the still only available BF4 benchmarks from Dice. Talk about bias... "AMD has decided to cobble a FX-8350 CPU with the high-end R9 290X to demonstrate the benefits Mantle would have."
First of all, these are NOT AMD benchmarks. These are from Dice, from the lead developer at Dice.
Secondly, cobbled? 'To make or put together roughly or hastily' So Johan
dug around in his rubbish bin and said... "what can we cobble together to make Mantle look really good?"
I guess nobody uses such a cruddy $200 CPU, and would be looking for a serious upgrade by buying a new $$$ GPU. Better to spend $$ on a new mobo and $$ on a high end CPU but stay with your current cruddy GPU. There must be an instruction manual somewhere that spells out proper CPU/GPU configurations and would keep me from making an embarrassing configuration faux pas. And no white GPUs past labor day.
Can you point us a link where and when they claim 1000000
draw calls ; i m quite sure that not only you could not provide
any source but still worse , this number doesnt come from AMD
but from here :

Actualy it s you who is making outrageous claims...
Actually it's you who comes here late and thinks he knows better
http://www.redgamingtech.com/amd-ma...100000-draw-calls-similar-to-ps4-api-library/
From 100 000 to 1 000 000 there s quite a margin, actualy AMD mentioned 9x the draw call count of current CPUs wich are in the 10k-15k bracket , that s
the number they target for current games , speculations from sites that
try to have an oversight of the evolution is another matter wich has
nothing to do with AMD current expectations.
I think you're crisscrossing things a bit. Mantle does not address CPU performance, it merely reduces the API overhead and makes things more streamlined, thus enabling faster communication with the GPU.
The CPU was never the problem. The problem was the overhead from the API.
Anyway, the CPU's workload is totally different from the GPU. With a GPU, you can nearly double your resources with a die shrink, and get nearly double the performance because the GPU's workload lends itself quite well to parallelism.
You can't do that with a CPU though, as their workload is more serial in nature.
And you're twisting it like there's no tomorrow. If we go by DICE's numbers a 3970X cut the CPU frame times in half using Mantle in the third example.
I don't really disagree with anything you say here..Then again Mantle is about parallel rendering too as explained several times already. That's why it likes moar cores. Looks like this is why every Mantlephobe was focusing on draw calls and neglecting every other API improvement, if I don't talk about it, it doesn't exist. Everything is in the slides from Mantle presentation so please read and understand it plox.
That's why parallelization is so important. I was actually kind of shocked when I saw that my performance in those screenshots I posted a few pages back didn't significantly decrease running my CPU at stock, compared to when it was overclocked to 4.5ghz, which implies that BF4 uses the CPU very well already.. I think I was only about 10 FPS off, and considering I was getting triple digit frame rates, that's not a whole lot.Adampa1006 is right and I agree and have said the same before. If we see a further +60% perf increase with 20nm GPUs the CPU side of things won't get such an increase with newer uarchs or die shrinks. That said I don't think we will see much higher CPU utilization in games since everything is stuck at DX.
This should be the first independent test:
