February 11, 2009 -- Back in September we reviewed the Sapphire Radeon HD 4670 graphics card that offered 512MB of GDDR3 memory. Overall, this RV730-based graphics card had performed well under Linux and not a bad investment with it retailing for about $80 USD. Sapphire Technology though has now introduced a new version of the Radeon HD 4670 that sports 512MB of GDDR4 memory. Will switching out the GDDR3 for GDDR4 memory have much of an overall impact on this graphics card? We have the results in this article.
December 01, 2008 -- We previously had looked at the ATI Radeon HD 4550 and Radeon HD 4670, but if you are looking for a graphics card that's positioned between the two and costs less, there is the Radeon HD 4650. The Radeon HD 4650 is clocked the same as the Radeon HD 4550, but is based upon the RV730PRO GPU and is able to provide a bit more processing power than the lesser RV710 solution. Sapphire though manufactures a Radeon HD 4650 graphics card that operates well beyond the reference core and memory frequencies for the RV730PRO and sells it at a very affordable price. In this article we are seeing how well the Sapphire Radeon HD 4650 512MB OC graphics card can perform under Linux.
November 18, 2008 -- For Linux desktop users interested in a mid-range discrete graphics card there are more choices than ever before with NVIDIA continuing to release new stable Linux drivers as they have done for many years while AMD this year has been making evolutionary leaps compared to their earlier state. AMD is now providing same-day support with all new products, CrossFire on Linux, OverDrive, and many other recently introduced features. NVIDIA and AMD are nearly at a feature parity and even in the past two months they both released new video APIs for Linux (PureVideo / VDPAU and X-Video Bitstream Acceleration, respectively) and they are now battling it out on Linux over performance. We recently looked at AMD's new ATI Radeon HD 4830 mid-range graphics card, but in this article we are comparing it to the NVIDIA GeForce 9800GT, courtesy of Micro-Star International.
November 12, 2008 -- The launch of the RV770 GPU earlier this year by AMD was quite successful. The Radeon HD 4850 and Radeon HD 4870 series feature best-in-class performance and Linux customers were greeted by an evolutionary step in ATI/AMD Linux support. Linux users with these graphics cards now have CrossFire, OverDrive, RandR 1.2, X-Video Bitstream Acceleration, and other new functionality. If you are looking for leading performance and all of the bells and whistles on the newest ATI graphics cards but at a lower cost, AMD recently introduced the Radeon HD 4830. In this article we are looking at the Sapphire Radeon HD 4830 512MB under Ubuntu Linux.
November 08, 2008 -- We've checked out ATI's Radeon HD 4550 low-end graphics card already and found it to be a nice solution for Linux users on a budget, but how does NVIDIA's competitor contend? In this review we are looking at the NVIDIA GeForce 9500GT from Sparkle. This graphics card has 1GB of DDR2 memory along with DVI, HDMI, and DisplayPort connectors.
October 24, 2008 -- Over the past few months we have looked at several Sapphire graphics cards including the Radeon HD 4670, Radeon HD 4850 Toxic, Radeon HD 4870, and Radeon HD 4870 Toxic Vapor-X. All of these cards have performed quite well on Linux with the Catalyst Linux driver and there is even open-source support for these R700 series graphics cards, except that goes without any hardware acceleration at this time. The graphics cards introduced up to this point though haven't exactly been cheap, but ATI has now introduced their low-end graphics cards for the Radeon HD 4000 series. With Sapphire being a key ATI partner, they have of course introduced news models accordingly. What we have our hands on today is the Sapphire Radeon HD 4550 512MB, which is a PCI Express graphics card that retails for a mere $50~60 USD.
October 14, 2008 -- The ATI Radeon HD 4870 graphics card arrived back in June with same-day Linux support through the Catalyst driver and there was even open-source mode-setting support. We have been very pleased with the level of Linux support for the Radeon HD 4000 series and it continues with features such as UVD2 and XvMC out on the horizon. With a few months having passed since the release of the Radeon HD 4870, we are starting to see more innovative RV770 products from ATI's partners. In August we looked at the Sapphire Radeon HD 4850 Toxic, which was a factory-overclocked Radeon HD 4850. Today we are looking at the Sapphire Radeon HD 4870 Toxic, which takes the original Radeon HD 4870 to the next level with heightened frequencies and an exclusive Vapor-X cooling solution.
October 07, 2008 -- Back in March we looked at the AMD Radeon HD 3200 graphics with AMD's 780G Chipset and found it to be a reputable performer. Its performance was almost identical to that of the discrete Radeon HD 2400PRO graphics card and was capable of running some Linux games at a playable frame-rate. Now though AMD's top-end IGP is 790GX Chipset with Radeon HD 3300 graphics. We have been testing an AMD 790GX motherboard from Elitegroup Computer Systems for the past several weeks and today we are delivering our Linux benchmarks of this newest AMD integrated graphics processor.
September 23, 2008 -- Earlier this month the ATI Radeon HD 4600 series from AMD was unveiled as the new mid-range graphics cards derived from their flagship RV770 graphics core. The Radeon HD 4650 and Radeon HD 4670 are the two RV730-based products now available. The ATI Radeon HD 4670 may not be able to compete with the Radeon HD 4800 series in all of the tests, but at a price of under $100 USD is it worth pursuing? For this article we have our hands on the brand new Sapphire Radeon HD 4670 512MB graphics card as we test it on Ubuntu Linux to see how well it can perform in our OpenGL tests and overclock with the recently added OverDrive support.
August 22, 2008 -- Earlier this week with the release of the Catalyst 8.8 driver we were first to deliver Linux CrossFire benchmarks for the Radeon HD 4800 series along with the first OverDrive for Linux article. With our initial CrossFire for Linux article we had delivered benchmarks from the Radeon HD 4850 and Radeon HD 4870, now though we are delivering the first Radeon HD 4870 X2 benchmarks under Ubuntu Linux. In this article we have our hands on the VisionTek Radeon HD 4870 X2 2GB graphics card.
