The latest addition to AMD's Radeon HD 4000 series (R700) family is the ATI Radeon HD 4770 graphics card, which was released in late April. We finally have our hands on this graphics card which uses the RV740 -- the first 40nm GPU -- and have proceeded to run our usual assortment of Linux-based tests. Along with the transition from a 55nm to 40nm process, the Radeon HD 4770 has been designed to bridge the current R700 solutions to their next-generation graphics processors that will be introduced later this year. The Sapphire Radeon HD 4770 may cost less than $100 USD, but it packs serious performance capabilities.

With the launch of the Radeon HD 4800 series in June of last year, AMD made an evolutionary leap in their Linux support. For the first time, when introducing a brand new graphics processor (the RV770) it was greeted by same-day Linux support, compared to the past where Linux users had to wait many months for any new level of support. Not only was there this Linux support via the Catalyst driver, but there was even open-source support in the X.Org driver the very same month. In the months that followed, they then introduced CrossFire support, OverDrive, and other features to put their Linux Catalyst suite closer to their Windows driver. This morning AMD is announcing a high-end refresh of the RV770 GPU that will be known as the RV790 and is found in the Radeon HD 4890 graphics card. Is AMD continuing to play ball with Linux? We will tell you this morning as we look closely at the ASUS Radeon HD 4890 on Ubuntu Linux.

Back in December we looked at the Sapphire Radeon HD 4650 512MB OC graphics card. This mid-range ATI graphics card had performed well under Linux and what separated it from the other Radeon HD 4650 graphics cards on the market was its factory overclock of 650/900MHz. While not factory overclocked beyond the RV730PRO specifications, PowerColor has the PowerColor SCS3 Radeon HD 4650 512MB, which instead offers passive cooling. Is this an ideal candidate for a Linux-based HTPC? In this article we are looking at the PowerColor SCS3 Radeon HD 4650 512MB.

The ATI FireGL graphics cards have been a staple of the workstation graphics scene for about a decade, but last year AMD made the decision to end the FireGL series and create the FirePro 3D series in its place. The FirePro 3D series is now made up of graphics cards ranging in price from under $100 USD and built using their RV730 GPU to their highest-end models costing well over $1,000 and using the RV770XT graphics processor. The ATI RV770XT is what is used by the consumer-grade Radeon HD 4870, which was greeted by same-day Linux support and other firsts for their Linux Catalyst driver like OverDrive, RandR 1.2 support, and CrossFire. The support for the new FirePro graphics cards is also first-rate under Linux with their Catalyst driver, but how is their performance? In this article we are examining the ATI FirePro V8700 1GB workstation graphics card under Linux.

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.

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.

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.

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.

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.

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.
