Sapphire Radeon HD 5850 CrossfireX

Testbed, Temperatures & Synthetic Benchmarks

Testbed

Our testbed has been configured such to avoid any potential limiting factors that may otherwise stunt the performance of the graphics cards being tested. This in turn may produce an artificial result that implies that CrossfireX offers minimal performance gains when infact it might be quite the opposite. With an Intel Core i7, cycling at a rather frisky 3400MHz we are not particularly worried about a potential bottleneck. All games are tested at a resolution of 1920x1080 .
 
Intel Core i7 920 @ 3.40GHz
Gigabyte EX58 UD3R LGA1366 Motherboard
6GB Corsair PC3-12800 DDR3 RAM
2x Sapphire HD Radeon HD 5850 1GB GDDR5
Antec Nine Hundred Two Gaming Case
Corsair HX750W ATX2.0 Power Supply Unit
500GB Seagate Barracuda 7200.12 SATA II HDD
LG 22x DVD+/-RW
Windows Vista Home Premium
 
 
Temperatures
 
 
 
During full GPU load, our Radeon HD 5850's had reached temperatures of 80*c. While this may seem high, it is well within operating temperatures. Furthermore, we are once again happy to report another quiet cooling solution on an ATi reference heatsink with Catalyst Control Center reporting Fan Duty speeds of just 33%.
 
Futuremark 3DMark Vantage
 
3DMark Vantage is an updated and more demanding evolution over the package that it succeeded. Our tests cover the "Performance" setting of the benchmark. The application will output three scores. The first two are CPU and GPU scores, which are formed from various tests that will focus on either of the two (or both). On the basis of those scores, a final "Overall" score is then outputted with a "P" prefix beforehand to denote that the "Performance" setting was applied.
 
 
 
 
In this Synthetic Benchmark, we see that the Radeon HD 5870 has a fair lead over it's stunted brother in both single and crossfire mode. The HD 5850's scores however are excellent for a £200 graphics card.

Ask any man, 1 is never enough. Mul puts a pair of fast women on the bench to see how 2 Sapphire 5850 shaped ladies perform under preasure.

Great review as usual Mul. The 5850's look like a good buy! They should be awesome around christmas when the price drops kick in, ATI's cards are the real working class hero's of graphics Quote

Cheers MeltedDuron.

As for price drops, I fear it may well go the other way until nVidia has a direct competitor. Given that the production of GeForce GTX 260/275/285's, VAT increases and a (currently) low supply of Cypress cards to meet demand, prices could even rise. We'll see how things pan out though.Quote
