Sapphire Radeon HD 4550 512MB

10/25/2008  
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.

AMD's MultiView On Linux

10/09/2008  
Introduced in the Catalyst 8.8 Linux driver and further stabilized within Catalyst 8.9 was AMD's MultiView technology. MultiView makes it possible to use multiple GPUs on the same system not for Linux CrossFire but for driving multiple display heads. Using MultiView on Linux you can easily drive four, six, or even eight screens. In fact, up to 32 displays are theoretically supported on a single system (permitting you have enough graphics cards and PCI Express slots). MultiView also allows for OpenGL acceleration across all displays and does not rely upon Xinerama. In this article we are taking a brief look at this multi-GPU multi-monitor feature catered towards AMD's workstation customers.

An Open-Source Radeon HD 4670? Sort Of.

09/16/2008  
When the Radeon HD 4850 and Radeon HD 4870 were introduced earlier this year, it was wonderful. These latest high-end graphics cards from ATI had same-day Linux support through their Catalyst driver and the open-source ATI drivers had "just worked" with the RV770 series. The mode-setting support with the xf86-video-ati and xf86-video-radeonhd drivers just required adding in the PCI IDs for these new PCI Express graphics cards and then the rest of the magic was provided by AtomBIOS. However, with the introduction of the Radeon HD 4600 series, not everything is working instantly with the open-source drivers.

Linux-powered LinPC desktop is a bargain

09/09/2008  
The new generation of inexpensive netbooks may be wonderful, but for my main desktop I want a real machine -- something I can open up, clean, and add to. So I was extremely tickled recently to trade for a new LinPC, an economical personal computer that features PCLinuxOS MiniMe 2008 preinstalled and ready to go. The LinPC's motherboard is an MSI K9N6SGM-V V2 in a Micro-ATX form factor. An AMD Athlon 64 X2 4800+ dual-core processor powers the system, aided by a gigabyte of RAM. It has a 1GHz front side bus and supports up to 2GB of DDR2 533/667/800 RAM. Included is a Realtek RTL8201CL Ethernet chip and Realtek ALC888 7.1 High Definition Audio. It has the standard ports, including four USB ports and six-port audio. The Nvidia MCP61P GPU is equivalent to an Nvidia 6100. Expansion slots are one PCI Express x16, one PCI Express x1, and two PCI (all open upon delivery). There are two memory slots, with one open.

This week at LWN: Interview: Kristen Carlson Accardi

08/10/2008  
Kristen Carlson Accardi is a Linux kernel developer for Intel's Open Source Technology Group. She is the maintainer for the PCIE hot-plug driver, the SHPC hot-plug driver, and the PCI hot-plug subsystem in the Linux kernel. She is currently working on SATA drivers, including implementing power management features. Kristen is the benevolent dictator for the upcoming Linux Plumbers Conference. We interviewed her about LPC, why so many Linux developers live near Portland, Oregon, and life as a kernel developer.

ASUS P5E64 WS Professional

08/09/2008  
Intel's latest performance desktop chipset is now the X48 Express, but there still is life left in the X38 Express, which was released late last year. The Intel X38 and X48 Chipsets share many of the same features including support for the latest dual-core and quad-core Intel processors, DDR3 system memory support, and 2 x PCI Express 2.0 x16 interfaces with there being very few differences to the end-user between these chipsets. In addition, benchmarks we have delivered from different motherboards have shown the X48 has little to no performance improvements over the older Bearlake chipset. ASUS's X38 motherboards are still very much in the market place and today we happen to be looking at one of their workstation motherboards based around the X38.

NVIDIA Launches 9500GT ($100) GPU

07/30/2008  
While NVIDIA's newest GPU family is the GTX 200 series, they aren't yet introducing the GTX low-end models but are continuing to mature the GeForce 9 arsenal. Introduced this morning by NVIDIA Corporation was the GeForce 9500GT, which is a sub-$100 product. The NVIDIA GeForce 9500GT has a mere 314 million transistors, its core is clocked at 550MHz, offers 32 stream processors, uses 256MB (though some AIBs may go for 512MB) of 128-bit 1600MHz GDDR3 memory, and is PCI Express 2.0 based...

SilverStone Decathlon 800W

07/09/2008  
Over the years we have looked at several power supplies from SilverStone through their Strider, Element, and Zeus series. All of these power supplies have generally performed very well and a number of them are still running strong within our test labs. SilverStone though has greater competition these days from companies like OCZ / PC Power& Cooling and Corsair. However, one of their newer power supply series at SilverStone is the Decathlon, which looks to appease users by offering a high-performance single +12V rail, support for up to six PCI Express power connectors, Active PFC, and a 100% modular cable design. In this review we are looking at the SilverStone Decathlon 800W power supply.
