Our HD 4890 CrossFire review investigates whether running two of these brand-new cards is a viable choice if you need that extra bit of performance or want to run with even more eye candy than what is possible with a single HD 4890 board.
Today NVIDIA released their GeForce GTX 275 Series. While there are no architectural improvements, the new cards offer substantially improved performance at competitive prices. Zotac's Amp! Edition offers higher clocks out of the box - is that enough to combat ATI's new offerings?
The HIS HD 4650 iSilence with its passive Zalman cooling solution offers a noise free experience, which is especially important when building a quiet media PC system. On top of that you will also receive a full version of the STALKER Clear Sky game.
In addition to the long and complicated name, the HIS HD 4870 IceQ4+ Turbo features twice the memory compared to the AMD HD 4870 reference design. The clock speeds have also received a boost, now running at 770 MHz core and 1000 MHz memory out of the box. Last but not least, HIS replaced the AMD cooler with their own IceQ cooling system.
While NVIDIA's GTS 250 isn't really new technology, Galaxy has chosen to put an Arctic Cooling Accelero Twin Turbo cooler on their card. Even though it uses two fans, the card is extremely quiet making it an excellent choice for a media PC. The best is that it won't cost you anything extra. Galaxy is offering their cards at NVIDIA's reference design MSRP of $149.
Today NVIDIA released their GeForce GTS 250 Series which is based on the G92 graphics processor that has already been used on a number of GeForce 8 and GeForce 9 designs. While NVIDIA's reference design comes with 1 GB of memory, Palit has chosen to create a card that comes with 2 GB of VRAM.
If you are looking for a quiet high performance card, then the factory-overclocked iChill GTX 260 is certainly a great choice for you. Using Arctic Cooling's Accelero XXX cooler it emits less fan noise than most low-end cards, yet offers performance close to the GeForce GTX 280.
Palit's new GTX 260 Sonic 216 SP is based on NVIDIA's latest GT200b 55 nm graphics processor. Palit has chosen to go with a dual fan design for improved airflow and increased overclocking. Not only the thermal design has been changed but also the PCB design, which features several cost optimizations and comes in an appealing ATI-red.
Zotac's GeForce GTX 295 comes with two NVIDIA GT200b GPUs sandwiched together in one graphics card. The card can successfully defeat ATI's HD 4870 X2 in our benchmarks and offers plenty of overclocking headroom beyond that. Thanks to the 55 nm GPU design and clever power saving methods the card even delivers in the performance per Watt segment.
NVIDIA's latest addition to their graphics card lineup is based around the 55 nanometer GT200b. The new card offers more performance, consumes less power and is quieter than the previous model. Yet these improvements cost you a premium of about $70 over the GTX 280. Is that price justified?
While many are satisfied with having a single screen, imagine gaming across 3 displays with 180° vision. The Matrox TripleHead2Go Digital overcomes the shortcoming of a single or dual display setup and gives you the possiblity to connect up to three DVI based LCD screens with a total resolution of up to 5040 x 1050 for real surround gaming.
Sapphire's new HD 4870 X2 Atomic Watercooled is a special edition of the popular dual-RV770 design that comes with a prefilled watercooling kit that also includes a waterbock for your processor. Being delivered in a nice aluminum case there are a load of extra accessories ranging from software to cabling - but the price tag is also outstanding: over $600.
Palit's new Revolution 700 Deluxe is the first graphics card that occupies three slots in your PC. The massive cooling assembly successfully increases overclocking performance, lowers temperature and reduces fan noise. But is that good enough to beat the AMD reference design?
The new Leadtek GeForce GTX 260 Extreme+ comes with an increased shader count of 216 compared to 196 on the regular GTX 260. Leadtek has also overclocked the card for some free extra performance. In our testing the GTX 260 Extreme+ delivers excellent performance per Watt claiming a number one spot in the test group.
Being priced at reasonable $419, the Sapphire HD 4850 X2 is designed to take some market share from NVIDIA's GTX 280. The card features 2 GB of GDDR3 memory and comes with a custom designed cooling solution. Even though you would expect very little overclocking from a dual-GPU card, we saw an amazing 15% performance increase from overclocking without touching any fan settings.
Sapphire's HD 4650 Overclocked comes with a solid overclock out of the box. But during our own overclocking tests we saw an amazing untapped overclocking potential resulting in more than 20% real world performance increase. Even without overclocking this card, that's in the $70 price range, is an excellent deal considering price/performance.
Today AMD launches their new HD 4830 Series. The cards come with a reduced shader count of 640 and lower clocks to fit into the $100 to $150 segment. In our testing we saw amazing overclocking of over 30% which should bring the card much closer to more expensive solutions.
PowerColor's new HD 4830 features the same 640 shader pipes as the AMD reference design, but comes with a big dual-slot cooler. Also new is a native HDMI output which supports HDCP and 7.1 channel audio. Thanks to a PowerColor designed PCB the card will retail about $10 cheaper than the reference design from AMD.
AMD's new Radeon HD 4550 comes in a passively cooled version without fan. Such a noiseless experience is crucial in media PC designs where you don't want to be distracted by any fan noise. Also included is a native HDMI and DisplayPort output for connection to your big screen. With a price of around $50 the card even offers some potential for casual gaming.
HIS' latest HD 4670 card comes equipped with the VGA Silencer made by Arctic Cooling. It also features an extra 30 MHz core clock. Even though it is factory overclocked we saw another 10% overclocking potential on both core and memory.
Sapphire has engineered their own version of the Radeon HD 4850 with cost and cooling in mind. The card's new unconventional heatsink looks good and keeps the card cool - far below reference design temperatures. The best of all is that the card costs only $169.99 online which makes it the cheapest HD 4850 available today.
Today NVIDIA released their updated GeForce GTX 260 GPUs which come with 24 extra shaders, for a total shader count of 216. Zotac has also overclocked their card beyond the GTX 280 clock speeds which results in a card that is just 1% slower than the regular GTX 280, yet costs over $130 less.
Today AMD launches their new cards based on the RV730 graphics processor. The Powercolor PCS HD 4670 we have on our testbench today comes with a dual slot heatsink which offers excellent cooling and low noise. Together with the serious gaming performance of this card, AMD has managed to successfully position their product in the sub-$100 segment.
HIS has just released the IceQ4 version of the AMD Radeon HD 4850. The IceQ4 cooler is a dual-slot solution which ensures low temperatures under both idle and load. Also HIS has overclocked the card which results in a nice performance boost compared to the reference design card.
NVIDIA's new GeForce 9400 GT Series is based on the same G96 GPU that is also used on the 9500 GT. The 9400 GT has half the shaders however, which seriously limits the uses of the card in a gaming PC. On the other hand this greatly reduces the heat output which allows a completely passive solution. Point of View differentiates their card by using 1 GB of video memory and bundling a full version of the Wall-E game.
