HD5670 vs HD4850 ?

[brianthesnail]

Hi guys
im currently using a XFX radeon HD5670 which im pretty impressed with.... for just under £60 it runs all games at medium to high detail but more amazingly at 1920x1080 resolution ..... however ive seen a good deal on a XFX radeon HD4850 and with a much better cooler i need to know if this will improve on the HD5670
ive looked at specs for each cards and they are as follows

HD5670 :
Core Clock: 775 MHz
Memory Clock: 2000 MHz (4000 DDR)
Memory Bandwidth: 64 GB/sec
Shader Operations: 310000 MOperations/sec
Pixel Fill Rate: 6200 MPixels/sec
Texture Fill Rate: 15500 MTexels/sec
Vertex Operations: 0 MVertices/sec
Process: 40 nm
Fragment Pipelines: 400
Vertex Pipelines: 0
Texture Units: 20
Raster Operators 8

HD4850 :
Core Clock: 625 MHz
Shader Clock: 625 MHz
Memory Clock: 993 MHz (1986 DDR)
Memory Bandwidth: 63.552 GB/sec
FLOPS: 1000 GFLOPS
Pixel Fill Rate: 10000 MPixels/sec
Texture Fill Rate: 25000 MTexels/sec
Process: 55 nm
Shader Processors: 800
Pipeline Layout: ?
Texture Units: 40
Raster Operators 16

as you can see the core and memory clocks are slower on the HD4850 .... however the HD4850 has a superior 256bit memory interface compared to just a 128bit memory interface in the HD5670
however the main improvements are the texture and raster units and the shader processors which are all twice as much with the HD4850 compared to the HD5670
so with the 256bit memory interface and the texture,raster and shader processor improvement would the HD4850 outperform the HD5670 ?
im not concerned about direct x 11.... to be honest when running games in direct x 11 i notice a significant performance hit.... so losing direct x 11 isnt a issue ....
so would the XFX radeon HD4850 be worth buying ?
any advice is much appreciated
cheers guys

The HD 4850 is a more powerful card than the HD 5670. To give you some perspective, the HD 5670 is roughly 30% better than the HD 4670, but it is slower than the HD 4770.

See following review:
http://www.techpowerup.com/reviews/MSI/HD_5670_1_GB/

A couple of drawbacks are:

1. Does not support DX11. However, the HD 5670 is too weak to make use of DX11 anyway for intensive games like Crysis 2 with the DX11 patch and high quality texture patch.

2. The HD 4850 consumes a little more than 2x the power of the HD 5670 and it also runs hotter.
