HIS Radeon HD 4890 Turbo Edition

Graphics Cards
The HD 4890 is ATI's newest GPU, on step beyond the HD 4870. It is the fastest single GPU graphics card produced by ATI. We're most interested in seeing if power consumption and noise level has improved over the 4870.

Sparkle GeForce GTS 250 1GB Graphics Card

Graphics Cards
The GTS 250 shares the same GPU core as the 9800 GTX+, a midrange gaming graphics card. Though the core is unchanged, the PCB has undergone some revision, perhaps to reduce power consumption. That could be one explanation for the smaller heatsink atop Sparkle's 1GB version of the GTS 250.

Asus EN9400GT Silent Edition

Graphics Cards
The Asus EN9400GT Silent edition is a passively cooled PCI-E graphics card based on nVidia's GeForce 9400 processor. If GeForce 9 was an office hierarchy, the 9400 would be its star mail boy. To differentiate itself from the other mail boys, it only has to be silent and power efficient.

Asus Radeon HD 4870 Matrix

Graphics Cards
The Asus Radeon HD 4870 Matrix features two fans without a restrictive shroud, giving the heatsink more room to "breathe", and providing direct airflow to the GPU and board components. By sharing the cooling work between two fans, it should be a quieter, cooler card. We pit the Asus Matrix against ATI's reference design.

PowerColor SCS HD4650: A Fanless Budget Graphics Card

Graphics Cards
The Radeon HD 4650 is a slightly cut-down version of the HD 4670, but still retains much of the performance of its bigger brother. The SCS is PowerColor's fanless version of the HD 4650, featuring a simple heatpipe cooler reminiscent of the Arctic Cooling Accelero series. Does it perform well, or is it simply adequate?

Asus EN9800GT Matrix Edition

Graphics Cards
Asus carries seven different GeForce 9800GT models; we chose to look at the Matrix Edition, which features a rear-exhaust cooler and numerous "Hybrid" themed features designed to appeal to a greener audience. Most intriguing is "Super Hybrid Engine" which purports to offer lower power consumption in idle and better performance and stability under load.

Filling the Gap: ATI Radeon HD 4830

Graphics Cards
The 4000 series video cards is one of ATI's most successful, and also one of the most wide-ranging. There's the HD 4870 X2 at the top — widely lauded as the current performance graphics champ — followed by the 4870 and 4850. With the HD 4670 at $80 and the HD 4850 at $170, it was logical for ATI to fill the price gap. At $130, the HD 4830 looks to follow in the tradition of its brethren and represent very good value.

Redefining Budget Gaming Graphics: ATI's HD 4670

Graphics Cards
The recently released HD 4670 graphics card offers a modern gaming experience with good eye candy support even at high resolution. We examine a reference card straight from ATI, one equipped with dual DisplayPorts.

Asus ENGTX260: A Quiet Graphics Card for Gamers?

Graphics Cards
It's huge, draws over 120W at load, ridiculously overpackaged, and illustrated lavishly when no one will ever see it once installed. But it has a secret card up its sleeve: The Asus nForce 260 based ENGTX260 could be the quietest stock high end gaming video card ever.

Diamond Radeon HD4850

Graphics Cards
The Diamond Radeon HD 4850 uses a cooling solution that looks virtually identical to the reference design, which is widely used by many card makers. This suggests that the acoustic, power and thermal performance of the Diamond, which we examine in detail, applies to many models featuring the HD 4850, already considered the best bang-for-the-money video card available today.

Asus EN3650 Silent Graphics Card

Graphics Cards
Asus is extending the use of its passive V-Cool heatsink down to a video card with a price tag that appeals to the masses, based around an ATI Radeon 3650 GPU. We know it won't be as fast as the 3800 series, but will it do high def video, idle at lower power, and stay cool in a low airflow system?

Asus EN9600GT Silent Edition Graphics Card

Graphics Cards
Asus has a large, growing stable of fanlessly cooled graphics cards. Their latest sports a sports car engine design theme on a GF 9600GT GPU platform. We take it out for a test drive.

ATI HD3850 & HD3870: Improved Acoustics & Power Efficiency

Graphics Cards
The Radeon HD3850 and HD3870 graphics cards finally put ATI in a competitive position against nVidia offerings in the all-important midrange market. They're also said to offer much improved power efficiency. We explore just how much, and the all important (for us) related issue of noise.

Updated VGA Card/Cooler Test Platform

Cooling | Graphics Cards | Reference|Recommended
The PC system used as our test platform for VGA cards and coolers was recently overhauled. The improved hardware and test procedures have made for a quieter, cooler system that should give us more consistent test results with a bit more ease.

Asus EN8600GT Silent/HTDP/512M Graphics Card

Graphics Cards
A fanless, silent version of the Asus 8600GT graphics card turned up in our lab recently. This is identical electronically to another Asus card we reviewed recently, except it has 512mb of RAM. Is the passive cooling solution good enough for a hot, low airflow, silent system?
