It is unfortunate but understandable that no names were revealed. I wonder if any malaysian websites were in the list...

This is why people should not buy into marketing hype.

Hehe. Anyone want to guess the clocks? There's enough information to estimate that from the first link alone
It's teraflops btw, not terabits.

This is what we know for sure so far.

R6xx/RV6xx common features:
UVD = Universal video decoder, supposedly 100% video decode offload even for h.264
Built in HD audio controller for HDMI output without needing extra cabling (!)
Dual link HDCP content output capable, (G80 can only output HDCP content at single link rates! Don't know if they changed this in the coming G86/G84)

R600:
80nm HS process
Smaller die size than G80
Single chip, unlike G80 which needs the NVIO chip
Built in audio controller(!)
320 scalar unified shaders/ALUs/stream processors
~16 texture units
~800MHz clock speed for top end
512bit memory bus
improved ring bus architecture

RV630:
65nm process
~150mm²
128bit memory bus
120 scalar unified shaders/ALUs/stream processors
~8 texture units

RV610:
65nm process
~80mm²
64bit memory bus (don't know if it can go up to 128bit)
40 scalar unfied shaders
~4 texture units

Interesting... so Capcom seems to think that the 360 GPU is extremely capable...

Sony uses a picture of PGR to advertise GT HD

ikanayam — Fri, 26 Jan 2007 06:05:58 +0800

Why would Sony use a picture of a 360 game to advertise Gran Turismo?

Too funny. Just too funny.

AGP 4x vs AGP 8x comparison

ikanayam — Mon, 02 Aug 2004 12:54:02 +0800

Seems that some people still have not gotten over this question of AGP 4x vs AGP 8x , so i decided to do some tests.

From what i see, the difference between 4x and 8x is generally insignificant other than with Far Cry. Future games will probably show a bigger difference.

System specs:
radeon 9800np (325/290), AGP aperture size at 256MB, fast writes ON.
Abit AI7 BIOS 17
2x512MB Kingston BH-5

P4 Northwood vs Prescott GUIDE

ikanayam — Thu, 01 Apr 2004 09:33:02 +0800

Many people seem to have no idea about the differences between the Northwood and the Prescott. This guide will hopefully give a rough idea about the performance difference (or lack thereof) between the Northwood and the Prescott P4.

Info from this thread is a result of compiling and analyzing data from various webpages and some intel tech documents.
Some of the references:

http://www.digit-life.com/articles2/rmma/rmma-p4.html

Below is a list of basic differences between the Northwood and Prescott. More details to come soon.
