ASUS EAH 6990 Review
|
 With the EAH 6990, ASUS presents its first AMD Radeon HD 6900
series graphics card featuring two GPUs. The successor of the already
very powerful Radeon HD 5970 lets us all hope for another superb
graphics card with excellent performance because it's a fully
functionnal dual Cayman XT (aka Radeon HD 6970) with high clock
speeds. We expect really good DX11 performance and we're going to show
you if the Radeon HD 6990 performs as well as an HD 6970 CrossFire
setup.

AXLE GT 430 Classic
|
|
"The AXLE GT 430 performed great. It didn't overclock past the ASUS variant, but it did run with a lower temperature while operating approximately as quiet as the CPU heat sink fans. The gaming potential is there somewhat, as long as graphics quality or frame rate isn't important — minimalism is key for gaming with this. High definition content handling is a great use for this card, as it is tailored to media workloads. This card also works great as a dedicated PhysX processor and can take the load off the CPU when decoding media content, while also completing the job faster!"

HIS HD 6870 IceQ X Turbo X Video Card
|
|
HIS HD 6870 Turbo cards are factory overclocked with a warranty. Now let me clarify something here. I said the HIS HD 6870 Turbo which is what we reviewed recently. HIS's Turbo X takes things to an entirely new level. The HD 6870 reference clock is 900MHz on the core and 4.2GHz on the memory. The HIS Turbo version of that card tweaks things to 920MHz on the core and 4.48GHz on the GDDR5 memory. With the IceQ X cooler, HIS takes things to the X level and jacks their card up to 975MHz on the core and 4.6GHz on the memory. That's quite a bump.

Radeon HD 6790 and Nvidia GeForce GTX 550 Ti
|
|
It's a blast from the not so distant past here at Neo today with our review of the Sapphire Radeon HD 5850 and HD 5830 Xtreme graphics cards. What's so Xtreme about cards that still use the reference specifications of the older mid-range Cypress GPUs models? Sapphire throws in custom PCB and thermal designs, not to mention Eyefinity and ATI Steam processing, to improve performance and pack more value into these Cypress-based cards. We put the Xtreme cards to the test to see just how well they compete against the likes of the Radeon HD 6790 and Nvidia GeForce GTX 550 Ti in the DX11 sub-$150 graphics card market.

Sapphire 5830 and 5850 Xtreme
|
|
“No, this isn't a review of two older graphics card models originally released a year ago. The Sapphire 5830 and 5850 Xtreme are actually two "new" graphics cards. More precisely, these are two previous-generation graphics cards that have been completely overhauled in design and are being released at extremely aggressive prices to compete against Nvidia's GTX 460 and 550 Ti mainstream lineup.”

PowerColor Radeon HD 6790 @ HT4U.net
|
|
PowerColor goes the way of working out an own design for the recently launched Radeon HD 6790 series to attract more buyers in the 110 Euro segment. HT4U.net shows the benefits of this effort."

Sapphire HD 6950 Flex Edition
|
|
"There are a few utilities available for overclocking graphics cards out on the web that for the most part work with most video cards. Many of the top manufacturers have their own utility and Sapphire is no different with its TRIXX utility. I have used this utility before and it is fairly straight forward to use. Sapphire has equipped the Flex with a Vapor Chamber-based cooling solution that allowed temperatures to hover around the 60 degrees Celsius mark when the fan was spooled up to 100%. This level of cooling let the HD 6950 Cayman core run up to 904MHz, or 104MHz over the baseline setting — this without the ability to increase the voltage on this card. The Hynix GDDR5 memory was able to scale another 255MHz over the as-delivered 1250MHz clock speed."

XFX HD6950 1GB Overclocked Edition Review
|
|
"Everything about this card is appealing — we see a visible and statistically significant increase in performance in the XXX Edition over the standard XFX HD 6950. The direct contact heatpipes do a good job at keeping the card cool under typical situations, however it becomes obvious that the performance of the cooler falls apart under a heavy heat load. This heavy heat load is from putting a huge overclock on the card and applying the extra voltage to the GPU. We see this in other "DirectCU" coolers, and they tend to fall apart in this same way."

NVIDIA GTX 590
|
|
" The headroom on the GTX 590 is at this point limited to about a 10 to 15% margin over the as delivered clock speeds, Even though the card supports voltage tuning. The overriding theme of this card is cooler and quieter than the competition. I did not have an overclocking utility to push the clock speeds above the 10 to 15% margins until late last night. At this point the overclocked testing had been completed but ASUS came through with their latest version of their Smart Doctor utility to help us out. With the stock voltages the maximum speed I was able to pull from this pair of GF 110 GPU's was 673MHz or right on that 10% margin. The memory was equally stingy at 1868MHz or 934MHz. At these speeds there was a definite performance increase that was noticed so overclocking is worth the effort and time to find the maximum clock speeds."

MSI GeForce GTX 580 Lightning review
|
|
We test and review the MSI GeForce GTX 580 Lightning. MSI peeked at the NVIDIA reference GeForce GTX 580, then took the GeForce GTX 580 GPU, and threw the rest away.
They designed a new PCB loaded with features and overclock potential, slapped some really cool memory on the card and topped off that GPU with the all new Twin Frozr III cooler.

Sapphire 5850 Extreme
|
|
Originally released in 2009, the AMD HD58xx series graphics card quickly gained popularity due to their ability to fully support DX 11, providing a completely new level of tessellation. Released in October of 2009, the HD5850 filled the lower end of the performance slot and was able to deliver great performance for its price. Originally, the HD5850 was oriented towards users who wanted that extra punch, but didn't feel the need to go overboard with their graphics. However, for those that wish to take full advantage of the HD5850, CrossFire is available, and considering the low price of the graphics card, this should be easily accessible.

AMD HD6790
|
|
'The AMD HD6790 is aimed to bridge the gap between the HD5770 and the HD6850. In essence it is a HD6800-card where AMD has just cut away some shader processors and som ROP's. We've put it through a series of benchmarks as well as overclocked it to see what it can do.'

HIS HD6850 and HIS HD6850 IceQ X Turbo
|
|
HIS has been making ATI and AMD cards for many years now. In fact, it is now almost exactly 7 years since we reviewed our first HIS card, the HIS Excalibur 9600XT Turbo VIVO Edition. As expected, HIS is fully supporting AMD's latest GPUs, and today we are reviewing two HIS cards using the HD6850 GPU: the HIS HD6850 and the HIS HD6850 IceQ X Turbo.
The HD6850 is in our opinion one of the more interesting GPU from AMD's HD6xxx series as it offers a very good performace versus price ratio. Not only that, as we will see in this review, the GPU also overclocks extremely well making its value even greater.

MSI GTX550 Ti Cyclone OC Video Card Review
|
|
After reviewing a few different GTX550 Ti graphic cards it does start to lose its flavor, especially when the results can be so similar. So it is a major relief to get a refreshing view of a reference card from MSI.
