Colorful has two diff coolers. Below is the dual-pipe version.

RV710 Architecture Disclosed

Radeon HD 4550 is going to ship at the end of September, but some of the documents have already been found, and the architecture of RV710 have been disclosed. The amount of transistors are 242 million, less than RV 730’s 514 million. This is because HD 4550 have only 80 shaders, and HD 4650 have 320 shaders.



There are two versions of ATI HD 4550, 512MB and 256MB versions. Both version have a reference board, 512MB is a full hight card and 256MB is a low profile. 512MB version have DVI/HDMI/DP output, and 256MB supports DVI/S-Video/D-Sub output. Both versions are running on 600/800MHz（Core/memory）.



Basically speaking, RV710 is a shrinked RV730, only two SIMD (single instruction multiple date) array, each of them have one texture unit. Inside each texture unit there are 4 Texture Address Unit, and 4 Texture Filter Unit. So in RV710 there are totally 8 TA and 8 TF units. Also there is only one Render Back End and memory bandwidth is lower to 64bit.

The price of Radeon HD 4550 512MB is about 49-59USD, and 256MB version is around 39-49USD.The rival of RV710 will be NVIDIA’s 9400GT.

Bottom line:
# It even beats the 9600gso which is a bonus (check anandtech for 9600gso getting trashed)
# It don’t need any power connector which makes it unique in that performance range (king)
# Is the best OEM/HTPC systems to this date. (king)
# Uses only 50/60 watts and is silent as a fart when am next to my galis.
# Less heat, more performance, DX10.1, silent, small, capable of 7.1 (sound) channel LPCM output over HDMI.
# Nvidia is going to use anther new sticker on old stock e.g. 9 series cards (9600gso), this time it will be the gt200 series e.g. gt260+.

well done AMD/ATi, its good for the customers (noobs), especially when they expect to buy new generation products (high number prefixes), with AMD that’s what they will get, unlike nvidia who use old cards with old technology but with new stickers (that’s a crime against knowledge).

They are conquering the GC world atm. No doubt. Until their rival wake up from sleep.

NVidia also fierce ma. Their pricing is scary.

Not a good merge, mod.
The 4670 thread should be merged into the main thread of 4000 series.

Cannot beat reference cooler.

Why not? Catalyst is a must for ATI.

OMG I gotta share it here.
Our OCer Henry managed to CF 4870x2 with 4850 OC.

It is not recommended to use an cheapo or so-called cap ayam psu due to its inconsistency of power supplied into the gc which might shorten the life of the gc. Get a better psu with at least a true power & higher efficiency.

Wait for the final release lor. More stable for sure

It is not advised to overwrite. Better remove the old one 1st//

What do u wanna know? I've posted few pages back in this thread.
No idea on its availability yet.

It's normal for me.
My Akasa Vortexx NEO is keeping the temp idling at 46C while 61C max when on load

550W should be enuf to power up to rig nicely.

Does this happen to 4870 too?

King of the Hill, 4870x2

COD4 utilizes quad-core & u gain extra fps from that.

4850x2 is still on hold, until further notice. The previous expected release date was end of September

Aiks Last night it was 8.9
