ATI Radeon HD 3670 aka RV635 Reviewed

Expreview published a preview of the ATI Radeon HD 3670 256MB aka RV635.Performance wise this card is not very impressive over Radeon HD 2600 XT.

The test result shows RV635 have a limited performance improvement.In almost all test subjects the card only outperform HD 2600XT less than 10% present which could be due to driver itself.

Two month after RV670’s debuting, AMD brings us RV635. RV635 is only a shrink version of RV630, AMD didn’t do many changes in its architecture, just adding DirectX 10.1, Shader Model 4.1 and DisplayPort support. So RV635, or HD 3670 is only a half gen evolution of HD 2600XT.

From the roadmap of AMD, we can see HD 3600 family will take the place of HD 2600 series. The price will be about 100USD. User will ask how much is the improvement? Actually not much. The average improvement is about 3%. Let’s hope it is just a another Catalyst issue, and AMD will rise the actual performance of HD 3600 series by releasing a new version of Catalyst in the near future.

The site also tested the power consumption and noticed that both in idle and load,the HD 3670 comsumes more power than HD 2600 XT.

First Benchmark Of HD 3650 aka RV635

Expreview published the benchmark of the next era mainstream GPU by AMD i.e RV635 or HD 3650.

RV635, the next era mainstream GPU by AMD, have been spotted benched using 3DMark05. Here is the score, 11001.

But source said he was using AMD OverDrive overclock the VGA card to 750/1650. So the score can not show what’s the chip’s real power.

RV620 And RV635 To Be Radeon 3x00

ATI will make quite a smart move that will boost sales of its entry level and mid range chips. Since it launched Radeon 38x0 series it slowed down the sales of 2600 and 2400 cards but it has a solution for it.

As people usually buy the cards with higher numbers RV635 will be renamed to Radeon 3x50 probably 3650 while the RV620 the 55 nm version of RV615 will be known as Radeon 3x50, most likely Radeon 3450.

These numbers look much better in the eyes of consumers and the new designation will probably help boost the sales of these chips. Smart but sneaky, what else can we say and it has been rumored that both RV620 and RV635 will get full DirectX 10.1 support and naturally they will consume less power and dissipate less heat due to the 55nm design.

AMD RV620, RV635 And R680 To Be Available Next Month

AMD announced its RV620, RV635 and R680 will all be available in January 2008.

Representatives from AMD would not confirm that the R680 is essentially two RV670 GPU cores on the same board, though the company did confirm that each core has the same specifications of an RV670 processor.


The RV670 graphics core, announced last November with the Phenom processor, is the first 55nm desktop graphics adaptor. AMD does not target this card as a high-end adaptor, though reviewers were quick to herald the RV670 as AMD's best product of 2007.

The company also made quick mention of the RV620 and RV635 GPU cores. These cores are nearly identical to the previous RV610 and RV630 processors, but will be produced on the 55nm node instead.
