Product information and further reviews for PCI-E graphics cards
HIS HD 4770 TrustedReviews 7/2009 - The original ATI HD 4770 graphics card uses a different cooler than the ones released by partners. Price and performance were the reasons given for swapping to a cooler cheaper than the ATI standard. Review details: Single Test. One graphics card was reviewed and rated on features, performance and value.
KFA² GeForce GTX 560 Ti 1GB LTD OC Bit Tech 4/2011 - As far as mid-range graphics cards go, Nvidia's GeForce GTX 560 Ti 1GB takes some beating. It costs less than £200, it's fairly quiet and it punches above its weight. It's proven itself to be the new mid-range king, and it's a great choice if you game at resolutions up to and including 1,920 x 1,080. Of course, there's one possible way to beat the standard GeForce GTX 560, and that's to buy an overclocked version such as KFA²'s new GeForce GTX 560 Ti LTD OC.
HIS Radeon HD 4770 PC Advisor 6/2009 - Messing up the naming system of graphics cards again, ATI's Radeon HD 4770 comes between the 4830 and 4850, with RV740 architecture, placing it as the successor to the 4650 and 4670 series. Its 40nm process though makes it more advanced than the 55nm of the 4830 and 4850. Review details: Single Test. One graphics card was reviewed and rated on build quality, features and value.
Sapphire HD 4850 X2 PC Advisor 8/2009 - Though the ATI HD 4850 X2 is no longer at the cutting edge of graphics cards, the Sapphire HD 4850 X2 with 2GB DDR3 RAM is a strong example of high-end cards, despite the little publicity it's received. Review details: Single Test. One graphics card was reviewed and rated on build quality, features and value.
Nvidia GeForce GTX 590 Expert Reviews 3/2011 - AMD's current flagship graphics card, the Radeon HD 6990, consists of two slightly underclocked 6870 graphics chips on one card. Nvidia's answer is the GeForce GTX 590, which similarly has a pair of underclocked processors in it – two GTX 580 chips running at 607 rather than 772MHz.
Sapphire HD 4550 512MB DDR3 Computer act!ve 4/2009 - With the increase in popularity of HD video, graphics card upgrades are now becoming common for this instead of just gaming improvements. The Sapphire HD 4550 takes the load of CPUs by handing graphics processing specifically for the latest codecs.
Zotac nVidia GeForce GTX 275 Amp! Edition TrustedReviews 4/2009 - Both Nvidia and AMD released graphics cards on the same day. The AMD one has already been reviewed, and here is Nvidia's GeForce GTX 275 Amp!, basically a cut-down version of the GTX 285, as overclocked by Zotac. Review details: Single Test. One was reviewed and rated on features, performance and value. An overall score out of 10 was given.
ATI Radeon HD 4770 PC Pro 4/2009 - The first consumer graphics card to use 40nm fabrication, ATI's Radeon HD 4770 has the RV740 chip at its centre. The smaller partner of the HD 4807, it keeps the same core clock and GDDR5 frame buffer, but cuts down everything else.
Sapphire ATI Radeon HD 4850 Toxic Edition PC Advisor 7/2008 - ATI's Radeon HD 4870 retook the performance crown from Nvidia and their latest graphics cards, however, in the mid-range sector, performance isn't as important as price and a difficult balance has to be struck. However, with its overclocked version of ATI's Radeon HD 4850, Sapphire is hoping to offers consumers that little bit of extra performance without exceeding the limit of what the average consumer will be happy to fork out.
nVidia GeForce 7950 GX2 TrustedReviews 6/2006 - Not too long ago, manufacturers such as Gigabyte and Asus made graphics card that took two nVidia chips and put them on to one card. My personal feeling on these is that they were pretty pointless as though you still needed an SLI motherboard you could only use one at a time, yet they cost the same as buying two cards. In the case of the Gigabyte, you even had to use a specific motherboard too. So when nVidia launched the GeForce 7950 GX2, I was instantly concerned as to its application.

We notify you free of charge about new tests on the topic of: PCIe GFX.
Your e-mail address:
In the early days of computers all graphics processing could be carried out by the processor itself, games were all two dimensional and resolutions were not high enough to tax the processor. As programmes began to be made ever more complex the processor had to dedicate more time to these and the need for a separate graphics processor became ever more pressing.
Early graphics chips focused solely on 2D graphics acceleration but the current need for lifelike 3D imaging has led to the development of chips capable of carrying out complicated lighting and physics calculations and generating full 3D worlds in real time.
All this information flowing between graphics chip and processor requires a very high bandwidth connection between the two. The first dedicated graphics port was the AGP port, an initialism of Accelerated Graphics Port. This offered a speed of 2.1GB/s compared to the then standard PCI with its maximum speed of 266MB/s. Eventually even this huge increase proved not to be enough for modern 3D games and a new standard was developed in the form of PCI-express.
PCIe can supply cards with 4GB of data per second and is fast becoming the standard in all modern personal computers. Apple switched to the exclusive use of PCIe in 2005 and most PC motherboards will come with at least one such port, either at 8x or 16x, some supporting two paired cards to offer the best possible performance.
The most up-to date graphics card will be DirectX 10 compatible, which will only be supported under Windows Vista but will offer users the best possible performance in modern games. Newer cards also use 'stream processors' which are processors that can carry out any number of functions rather than be bound to a specific process and left idling when not in use.
A basic card can be bought for as little as £30 whereas a high-end model will be nearer £300.
