With the R7 250X OC video card, Gigabyte succeeds to provide for the entry-level market a competitive card which can run games at either medium or high detail levels, while using display resolutions up to 1680x1050. Plenty of connectivity options are also offered, along with a dual-slot cooling system which remains silent at all times.
Today we have not one, not two but three GTX 580's on our test bench and we will be running them through a huge amount of real world testing to show everyone reading the complete picture of GTX 580. From standard gaming at 1920x1080 to surround gameplay at 5760x1080. 3D Vision to Blu-Ray 3D via a comparison with AMD HD3D. GPU computing and PhysX... F1 2010 with the DX11 patch and even Call of Duty: Black Ops... It's all here in comparisons which include the GTX 480, Radeon 5870, 5870 Crossfire, 5970 and 6870.
Today we are looking at the latest card from Gigabyte, the HD7870 Overclock Edition which is supplied with a custom cooler, comprising not two, but three fans. This is the first custom cooled HD7870 we have looked at since the launch of the reference card on March 5th. Gigabyte claim the card is almost silent thanks to a proprietary ‘anti turbulence’ fan design.
Today we are reviewing a new card from Gigabyte, the HD6770 Silent Cell, which is a passively cooled discrete graphics card built on a 2oz copper layer with full overclocking capabilities. Gigabyte also claim that temperatures with this design be reduced by 10% when compared against the reference solution. Is this an ideal graphics card for a low noise performance PC?
AMD’s HD 7790 graphics emerged on the scene roughly at the same time as Nvidia’s GTX 650 Ti Boost graphics card. The AMD HD 7790 was released to fill that rather large performance void left between the HD 7850 and HD 7770 using a specially designed GPU called Bonaire. The Gigabyte graphics card that we have here today represents the HD 7790 pushed to the best it can offer. We have Gigabyte’s 2GB variant of the HD 7790 with the WindForce cooling solution and a factory overclock, more specifically we have the GV-R7790OC-2GB Revision 1.1 graphics card.
We say its the “best that the HD 7790 can offer” because Gigabyte have maxed out supported GDDR5 memory by adding 2GB and they have put a rather beefy dual 100mm fan WindForce cooling solution on it. Furthermore, Gigabyte have taken the stock clock of 1GHz and raised that by 7.5% to 1075MHz. The 2GB of GDDR5 over the 128bit interface runs at the default 6GHz effective memory speed, so no overclocking there. Despite the overclock Gigabyte have recommended just a 450W power supply as a minimum for this unit while AMD recommends 500W.
In terms of features this card packs most of AMD’s high end features such as Direct X 11.1 support, GCN architecture, AMD Eyefinity support (up to six displays supported), AMD App Acceleration, AMD HD3D technology, AMD CrossFire (max 2 way), AMD PowerPlay, AMD PowerTune and AMD ZeroCore. The main stand-out features are Eyefinity and HD3D support on such a budget GPU.
Today we have a couple of customized solutions based on the Radeon HD 5870 GPU. Both have proprietary coolers, and Gigabyte's card also has an original PCB. Besides, both graphics cards are factory-overclocked.
Whew, it has been a long time since we last reviewed a video card. I am not even going to bother linking to our last article on graphics to give you an exact time gap between this review and the last. With the past now behind us, I am very proud to announce we are now back on board with the component essential to all gaming computers -- and we will have many more to come, too. I still remember a few years ago when a midrange video card meant playing most computer games at midrange settings. You might get a shot at maximum settings if you were playing an older game. Own a big monitor? Cough up more cash, or turn down the resolution and detail. But times have changed. Today's midrange performance cards in the $200 range provide surprisingly excellent bang for your buck. AMD's 40nm Northern Islands family of GPUs is the company's second generation DirectX 11 cards, and the 6850 and 6870 -- codenamed 'Barts' -- promise to deliver roughly the same level of performance as the 5850 and 5870, which were the high performance graphics processor units of the previous generation. (Just to clear up the name confusion, the 6800 series replaces the 5700 series; the 6900 series replaces the 5800 series.) With so many variants of 6850s to choose from, manufacturers scramble to differentiate their products from their competitors. The Gigabyte GV-R685OC-1GD Radeon HD 6850 1GB OC is a perfect example. Featuring Gigabyte's Windforce 2X cooler out of the box, as well as a slight factory overclock to give it an edge in the benchmarks, is it enough to set this product aside from the other 6850s? Read on to find out!
Enter Gigabyte and the GVR587SO-1GD videocard, which increases the Radeon HD 5870's core clockspeed from 850MHz to 950MHz, increasing the effective frequency of its GDDR5 memory from 4.8GHz up to 5GHz. This beauty of a videocard uses a custom dual-fan heatsink design for better cooling and takes advantage of Gigabyte's Ultra Durable VGA+ manufacturing techniques.
PCSTATS is testing out Gigabyte's GV-R477D5-512H-B Radeon HD 4770 videocard alone, and in Crossfire mode so you'll know exactly what two of these mainstream cards can do for you! We already know one Radeon HD 4770 graphics card offers great performance for under a hundred bucks, the real question is what level of gaming performance will two 4770's teamed up under Crossfire deliver?
The Gigabyte GV-R435OC-512I is a half-height PCI Express x16 videocard designed for small form factor and home theatre PCs that need a bit more horsepower, HDMI output, or both. It has DVI, VGA and HDMI output, and can do audio thanks to an on-board codec. This videocard also supports HDCP, so it'll play nicely with your protected Blu-ray discs.
