Let's have a closer look at the 4670's specs, ATI Radeon HD 4870. AMD Catalyst Performance Patch For Legacy GPU s 17/JAN/2013 Discussion in 'Videocards - AMD Radeon Drivers Section' started by ankinferno. This diverse series developed by Boundless Network. The Radeon HD 4650 1GB is clocked at 600 MHz. ATI Radeon HD 4650 is, the development progress of controllers. The spec sheet mentions 480 gigaFLOPS, 32GB/s of memory bandwidth, and a 59W power envelope for the 4670, compared to a respective 429 gigaFLOPS, 53GB/s, and 95W for the Radeon HD 3850. Built on the 55 nm process, and based on the RV730 graphics processor, in its RV730 XT variant, the card supports DirectX 10.1.
The card makes use of Unified Superscalar Shader architecture, and it is produced on 55 nm manufacturing process. We've had a couple of Mobility Radeon HD 46 class reference cards in house for a while now, and have a sneak peek at approximate performance using a desktop platform for testing on the pages ahead.Download Now ATI RADEON HD 4650 MOBILITY DRIVER The reference card pictured here is equipped with every type of output supported by the GPU-Displayport, DVI, VGA, S-Video / HD component, and HDMI-and it even has CrossFire connectors for experimenting with multi-GPU configurations. We talked about the new mobility Radeon HD 4000 series during CES earlier this year more details are available at this link. The item pictured below is an ATI Mobility Radeon HD 4670, PCI Express-based reference card. What you see pictured here is just such a card. The cards won't be used in any actual retail product, but they allow AMD to test all of the various features and functionality, and experiment with clock speeds and voltages to fine tune and balance performance, thermal output, and power consumption.
One of the ways AMD is able to test and qualify ATI Mobility Radeon GPUs, without having to design and build numerous mobile reference cards that fit in multiple notebook form factors, is to produce fully-loaded, custom reference cards that'll fit into standard PCI Express x16 slots.
