Let me get this straight: we're supposed to just post news, and not discuss it? That's a pretty odd view to hold, given that this is a forum, and all.

Let me get this straight: you think this is a discussion? That's a pretty odd view to hold, given the amount of crap posting from rabid AMD and Intel worshipers, and all.

Battlefield 4 1080P at Medium according to the AMD presenter. Which falls into line with what the standalone 7750 DDR3 can do:

http://www.hardware.fr/focus/76/amd-radeon-hd-7750-ddr3-test-cape-verde-etouffe.html

24FPS Battlefield 3 1080P Medium Radeon 7750 DDR3 + stock i7-3770K

I'd imagine the card is bandwidth starved at Medium, so doesn't reveal anything regarding the CPU side of Kaveri. Especially since they didn't show a combat scene.

I dont understand a thing you say. Are you comparing bf4 results to bf3 results?

the most important question for kaveri is whether they have significantly improved the memory subsystem, because honestly the a10-6800ks gpu is very capable, just very starved for bandwidth. Maybe hq[hetero queuing] allows the gpu to use the cpus caches to help alleviate the bandwidth issue even if just a few percent.

That is the million dollar question. HQ in theory has the potential to provide a massive performance boost. Combine that with the fact that you dont have to copy buffers and can just pass a pointer around... that could be huge.

Yes, I think the BF4 non-combat scene (as shown by AMD) is not going to be much more demanding than a BF3 bench at same settings. AMD did not provide any demonstration of fighting in BF4 on Kaveri.

So now we pretend the 6800K doesnt exist? You know, with a 4.1Ghz baseclock. But whats a 400Mhz drop between friends.

So lets see:
No 3M/6T models.
No quadchannel.
Slower IGP clock than expected.
Slower CPU clock than expected.

Did I miss anything? Besides the usual nonsense about the next AMD uarch will really beat Intel this time?

Only that the CPU clock actual came in around expected (10% lower going to Bulk). Which I was starting to doubt was going to happen. GFL did alright (assuming decent yields).

Other than that, yeah, we are waiting for Excavator to deliver the APU AMD really needs now - but that's life at the shallow end of the pool.

Why not comparing it to Batman Origins? These are two different engines!

I'm pretty sure that still qualifies as a discussion.

Quad channel for GDDR5 (4x32bit) is there, taking die space ;). This won't go away as its part of the IMC. It's not a huge die are that is wasted tho so no biggie :).

What evidence do you have to support these claims?

BF4 is much more demanding than BF3.

Compare the numbers for Titan in these benches:

bf3-1920-average.png


1080p Ultra, 95-114 FPS in BF3 and 68 FPS in BF4.

Kaveri is just 10% slower clock wise, that's peanuts considering they are working with a new uarchitecture with big core changes and done on a new node

That's a good point. Hopefully they'll manage to ramp the maximum clock speeds back up as the Global Foundries 28nm process matures.

Quad channel for GDDR5 (4x32bit) is there, taking die space ;). This won't go away as its part of the IMC. It's not a huge die are that is wasted tho so no biggie :).

I hope this is true, but like many of the other posters, I'd like to see a citation for it.
How would this work, anyway? GDDR5 isn't (currently) available in DIMM format. Would you need to buy a special FM2+ motherboard with the GDDR5 on-board? How much extra would that cost - assuming the same RAM would be used for both CPU and GPU, you'd probably need 4GB+ for a decent low-to-mid-range system.

Because same developer and same overall game type makes a lot more sense? Heck it's not as if they didn't reuse assets...

Radeon 270X

Battlefield 3 1080P Very High FXAA/16xAF ~60 FPS

http://www.techspot.com/review/722-radeon-r9-270x-r7-260x/page3.html

Battlefield 4 1080P High HBAO ~60FPS

http://www.techspot.com/review/734-battlefield-4-benchmarks/page3.html

You are welcome to test BF4 1080P Medium non-combat scene vs BF3 1080P Medium combat bench yourself and report back.

Ok, this thread is lost. Between the fanboys on both sides, the mild insults, threadcrapping, and off-topic posts, this thread is done. If someone wants to start a new one, and try to be civil, I will leave it alone. Your only other chance is for me to infract almost every poster in this thread.
