AMD's ATI Radeon HD 5450 Video Card Review

AMD's lowest-end discrete GPU to support DX11 is being launched today at $49-$59 MSRP, the ATI Radeon HD 5450. We will give you all the official information on this new video card, plus some power and temperature testing and a simple apples-to-apples DX11 game test using DiRT 2.

Introduction

Today, AMD is launching the ATI Radeon HD 5450. The ATI Radeon HD 5450 is previously known as the codename "Cedar." This is AMD’s slowest and cheapest discrete GPU to be released supporting full DX11 and Eyefinity support based on their latest generation of GPU technology. MSRP (depending on add-in-board options) will range between $49-$59. This is by no means meant as an enthusiast gaming solution as our readers are typically interested in. Therefore, we will simply post the official information for your reading pleasure and run a few quick power, temperature and apples-to-apples test in DiRT 2 to see if DX11 support works, and to see how it scales in comparison to the ATI Radeon HD 5670 (which sits right above it right now.)

To summarize features, the ATI Radeon HD 5450 is made up of 292 Million transistors on the 40nm manufacturing process, has 80 stream processors, 8 texture units and 4 ROPs. The GPU runs at 650 MHz and memory is comprised of either DDR3 or DDR2 and can run up to 800 MHz (or differently based on add-in-board partner specifications.) This provides 104 GFLOPS of performance, a 5.2 GTexels/s texture fillrate and 2.6 GPixel/s pixel fillrate. Bandwidth would be 12.8 GB/sec at 800 MHz based on the 64-bit memory controller. Important for this level of video card the idle power utilization is a low 6.4 Watts and typical board power is 19.1 Watts under load.

Due to these low power specifications, only a passive heatsink is required to keep this GPU cool. That means that the ATI Radeon HD 5450 can operate in a complete "silent" computer solution. No external power connection is required. Eyefinity is also supported for 3 displays at 2560x1600 each. For HTPC users note that there is full support for HDMI 1.3a with Dolby TrueHD and DTS-HD Master Audio.
