Conclusion: While ATIs RV770 and RV790 have undoubtedly brought them firmly back in the game, we have always been concerned about the noise and heat they produced. Not that modern high end Nvidia graphics cards are a lot better, but the argument for ripping off that noisy air cooler and finding an aftermarket...
Summary: After a series of tests we found the card to be a stable GPU that runs cool, stays silent (for the most part) and handles quite a load graphics wise. The frame rate in the majority of games came out excellent.
Summary: It looks like Sapphire has struck gold with their HD 4890 Toxic Vapor-X. The card offers considerably improved performance over the HD 4890 reference design and can beat the GeForce GTX 280. It does all that without being noisy, it is much quieter than all other HD 4890 cards I tested so far.
Pros: Quiet, High default clocks, Voltage control support for memory and GPU voltages, Six + Eight-pin power connector, Nice aesthetics
Cons: Very limited overclocking potential, No support for CUDA / PhysX
Summary: The bottom line on the Vapor-X Radeon HD4890 1GB graphics card is that it offers high end performance with minimal noise; two items near the very top of my checklist of things to look for in a graphics card.
Pros: » Factory overclocked, but capable of running even faster, » Impressive performance in benchmarks and games, » Integrated DVI, VGA, HDMI, and Display Port connections, » Some hot air is exhausted out of the case, » Automatic fan control keeps card very quiet
Cons: » Power hungry, » Automatic fan control lets GPU get to 85C before ramping up, » Premium features come with a premium price tag
Conclusion: Many of you will say, “All the HD 4890 is, is an overclocked HD 4870″. In some regards you are right. But who honestly runs 850MHz core on an HD 4870 without extreme cooling? Not even my non reference HD 4870 can get through a round of Vantage, let alone, being stable.
Conclusion: It feels like an age since we last saw a genuinely brand-new architecture from either AMD or NVIDIA, and if that's what you're looking for from this launch then I'm afraid it's time to be disappointed.
Conclusion: We mentioned at the beginning of this review that in today’s marketplace innovation through the maturing of existing technologies would be the way to success. Even though their new architecture is still some time away, ATI knew that they needed a card placed between the HD 4870 1GB and HD 4870 X2 to...
