CF/SLI review incoming?
also you might want to check latest prices - the one suggested in the article @ scan isnt what they are charging today when they are on sale....
Will be waiting for better BF3 drivers and the Windforce/Frozr cards myself.
Nope, but it *is* what ebuyer are charging ;)Quote:

The Sapphire Radeon HD 7970 graphics card is available to purchase from scan.co.uk
how is the fact that it's £200 more for not that much of an improvement in performance not in the bad section ?
really need to see the XF results for 6970s, for £50 more you could get what, 40% more performance than tha 7970 ?
Because it's the fastest card out there. If value worked linearly then we'd all be using intergrated graphics or something - anything other than bottom end costs more than it gains you percentage wide. Add in early adopter markup and it's even more explainable. Just look at what's happening in the markets - people are actually willing to pay more than the original selling price to get one, hence prices are actually increasing.Quote:

My mates taking delivery of his Sapphire 7970 shortly then I can have my 5770 back and replace my 4770 I'm currently stuck with
Look at the benchmark results. The card is seriously under-performing on the Frostbite engine compared to all the other results.Quote:

That's true. Some people from AMD have hinted it's not a driver thing though - it's the way the engine is coded - a patch would need to come from Dice.Quote:

Using the 580 as a benchline in DX10 (I can't get DX11 to appear) it scored 60.3 FPS in 2011 at 1920*1200, and 41.7 in 2012. A factor of 1.446, which I can't explain....Quote:

I'm using the Iron browser, and no longer get that one. I get it every time in FF and infrequently in IE.Quote:

Well it's true and reasonable in both cases. For Bulldozer you've got a new type of processor that doesn't behave either as a pure full cores chip or as a combination of full cores and SMT, we've got modules that work differently. The way PCs are currently designed the OS is responsible for the threading, so either you have to go back a step and stop presenting cores to the OS (and thus applications) or you have to add a bunch of transistors to the CPU that has to gather up all the OS requests and re-sort them into better ways of doing it - that's a waste of transistor budget when it's something that can be fixed in software.Quote:

Again, maybe AMD *could* do some driver magic, but it's possibly too late by that stage, the calls from the game are the better place to fix it.
Everytime in the last 20 years when desktop CPUs had major changes Windows throws a hissy fit.Quote:

The Pentium Pro proved its worth with Win98 and was the basis of the Pentium 2 and Pentium 3. Its innovations live on in virtually every desktop CPU today.
2.)Athlon 64 - 64 bit extensions and integrated memory controller. At launch these were considered rather irrelevant at the time. 64 bit support by WinXP and applications was poor. Yet,look at how the situation changed in only a few years.
3.)Athlon X2. First production dual core for the desktop. WinXP had major hissy fits with this and so did many applications due to scheduling issues. It took software patches which revealed its true worth - people still use this CPU even today.
4.)SMT. Digital Research were to implement this with a version of the Alpha which never saw full production. Intel brought it to the market with the P4. SMT caused major issues with XP and multiple applications. Patches improved performance,but it took until Vista and Windows 7 for SMT to shows its true potential. Both IBM and Sun Microsystems use SMT in their server CPUs. The IBM CPU in the XBox360 uses SMT too.
5.)CMT. The first major architectural change for desktop since SMT was introduced with P4. Guess what?? Software support is immature just like in the previous examples.
Got the DX11 to work !Quote:

Using Metro 2033 across 2011/12, at 1920*1200 and VHQ, a similar method to above, the 5870CF is better than a 580, but less than the 7970.
Anand's GPU Bench 2012 quotes 44 FPS for the 580, 54 for the 7970. On that basis the CF5870s should pull 50 FPS.
Its very nice but way to expensive to justify. I think I will stick with my duel 6950 until the next generation comes out or they start to struggle.
"for its the first single-GPU Radeon that makes a reasonable fist out of 5,760x1,080 gaming."
You mean reasonable first, right?
The phrase is make reasonable fist of it - ie have a good go at it.Quote:
