â—† RV635 details
GPU-Z can detect RV635 but fail to recognized it as HD 3670.
Architecture of RV635 is similar to RV630. It have Unified Shader Architecture, integrated with 120 Streaming Processors, 16 Texture Address Unit, 8 Texture Filter Unit and 4 ROP. RV635 supports 128-bit, can equip with GDDR2 GDDR3 and GDDR4.
RV635 technical specifications：
· ATi® Unified Shader Architecture
· DirectX10.1/Shader Model 4.1 support
· PCI Express ®2.0 support
· ATI PowerPlay™ energy conserving technology
· 55nm process technology
· 120 stream processing unit
· ATI Avivo™ HD video and display technology
-Built-in DisplayPortâ„¢ technology
-Built-in HDMI and 5.1 surround audio
-Support for the ATI Radeonâ„¢ DVI to HDMI adapter
-Unified Video Decoder(UVD) for Blu-rayâ„¢ and HD DVD at full HD 1080P
· 128-bit memory interface
· ATI CrossFireX™ multi-GPU Support
-Compatible with motherboards that support ATI CrossFireX technology
core shot of RV635
RV635 GPU is made by TSMC’s 55nm process technology. Same as RV670, all cards of HD 3600 family did masked any stream processors. So all HD 3600 cards are 120 steam processors. But the frequency are vary.
AMD’s VGA flagship HD 2900XT(R600) have 320 SP, mainstream HD 2600(RV630) have 120 SP. And now the new RV635 have the same SP number. Will RV635 perform the same as RV630’s?
AMD have two version of RV635, one is Pro(core/memory: 600MHz/1000MHz),will be named as HD 3650. The other one is XT(core/memory: 800MHz/1600MHz) will be called HD 3670.
HD 3670 will hit the market in late January. And HD 3650 will begin selling in late February.

Due to NDA, we can not release card pics of Radeon HD 3670. However we have core shots and memory shots;)
Radeon HD 3670 supports Dual-DVI, Video-IN, HDMI, DisplayPort and other video output solution. We can expect other manufacturers rolling our their DVI+HDMI+DisplayPort non-reference version in the near future.
Radeon HD 3670 uses Samsung 1.0ns GDDR3 memory chip. The code is K4J52324QE-BJ1A, 4 in front and 4 in the back, totally 8 32bit*16M chips and make the total memory 256MB/128bit. The default frequency of Samsung 1.0ns memory chip is 2000MHz, but AMD sets it to 1600MHz, reserve some rooms for users to overclock.

Rumor has it that this card will retail for about 50 euros. If that is truelly the case then this card is ok. You can play episode 2 at 1600*1200 so it will be ok for a small number of older games.

Try also the fur stress test of GPU Caps viewer to heat up the gpu: http://www.ozone3d.net/gpu_caps_viewer/

The 1600×1200 resolution test shows that the new card’s 128bit memory interface is not sufficient for 1600×1200. The older HD2600XT has 256bit memory interface. Basically the card is for 1280×1024 no AA no AF setting only(basically for those idiots who own 17 or 19 inch LCDs. People with 20+ LCDs would buy the 8800GT and enjoy games the way it’s supposed to be played.
ATI can pump out castrated video cards all they want with bigger marketing number, it only makes geeks hate them more.

Not all of us on 19inch monitors are idiots. Sometimes there are limiting factors like supply problems or rediculous prices on 20+ inch monitors in some countries. Hell my 2 8800GT graphics cards costs the same as a 22inch wide screen at some suppliers. So please hold of the generalizations.

@my mini-me Doug:
Hey, mini me. In the US, 24 inch 1920×1200 monitor can be had for $299. A 17 inch LCD is $179, and a 19 inch is $200-$250 depending on brand. So in the U.S., we are predicting that anything less than a 24 inch will be phased away into third world countries.
January 11th, 2008 at 3:50 pm
If you believe that the smallest LCD people will buy is the 24 inch LCDs(and prices will continue to drop, and it will be $150 in a year or so), then a graphics card needs a minimum 512MB of frame buffer memory for the 1920×1200 and 256bit memory bandwidth. Therefore, the cheapest card to drive those monitors are the 512MB HD3850 for $199. Anything less will be obsolete simply due to display requirements. But at that price levels, people will opt for the 512MB Geforce 8800GT for $50 more.

JeGX, thanks, that’s a awesome OpenGL tool for us!

Doug: Sorry about the name thing. Not enough coffee in my system to read the form properly…
Sadly I live in South Africa… A 24inch monitor directly from the supplier is R5500 + vat (14%) (+/- $900)…
19inch monitors are out of stock everywhere leaving us with 17inch for about $200 + vat when its available…

@Doug Friedman:
Who told you, the HD2600XT would have a 256bit memory interface?! Bollocks…

i guess that the fault lies in the drivers… no other reason…
