any idea of d rv740..???4750?

Not surprising since they have good connection with Gigabyte.

Retail price RM 1099 if i not mistaken. And still can go lower from what i hear.

Ya you are right. i think the top version available for 1 GB as well.

thank for the link

Lol, i don't want to try... hehe i want to check the game score first and compare it to 4870. if its worth, than i'll buy.

if only 10~20% improvement, i probably don't buy.

If they slash the price of 4870, then i will CF mine

I bought a HD4850 1gb a few months ago...

Planing to CF it soon.... Must I CF with another HD4850 1gb or a 512mb will do??

And can I CF with a diff GC for example a HD4870 or HD4890??

So far, chart for 4890 have not released yet. For sure, but i can give you a NO.
usually must be a same chip.
Example,

Card 1 = 4870
Card 2 = 4870
or
Card 1 = 4870
Card 2 = 4870 X 2or other way

or both X 2 = quad core.

Anyway, read more here:
http://game.amd.com/us-en/crossfirex_about.aspx
http://game.amd.com/us-en/content/images/c...combo_chart.jpg

i think 512mb also ok cause in CF mode... it no share the 2nd card ram... it only share the Core for graphic Processing....

BTW correct me if i am wrong

Thanks for the clarification....

I thought i read somewhere that you can CF a card similiar to the one you have, so i thought the 4850 is part if the HD4800 series and therefore CFerble with a diff 4800 series card... Lol...

Guess I thought wrong...

err
4850 can be CF with 4870 or 4830, but cf with 4890 still not confirm yet

bro the red coloured square means can CF without problems. but AMD recommends Cf'ing with 4850 or 4850X2 (which is the read square with dot in it)

guys how much the drop price for 4800 series?

Someone tested it, 990Mhz on stock cooling.


After using water and more voltage, 1.2Ghz!

link plz

link down. NDA poliz caught back.

But it's real, definitely. Novatech forums.

What is NDA actually?
Stock cooling at 100% Speed?

Non Disclosure Agreement

hope to see the review soon,
4890 vs 285gtx ho ho ...then i'll decide to take which camp =_=

I doubt it can beat GTX 285. it will be in the same league as GTX 275 or GTX 280

Someone copied the Nova page before it was removed. Wheee.


Intel Core I7 920 @ 3800MHz
Asus Rampage 2 Extreme Mainboard
Corsair Dominator 1600MHz 6GB Triple Channel Kit
PowerColor ATI Radeon 4890 1024MB / Asus NVIDIA GeForce GTX 285 1024MB
Windows Vista 64-Bit Ultimate
Both cards using supplied drivers

3DM06
GTX 285: 20275
HD4890: 19321
HD4890 @ 990/1150: 21203
HD4890 OC CFX: 24538

Vantage with PhysX
GTX 285: P14699 (CPU - 50551, GPU - 11889)
HD4890: P11160 (CPU - 17378, GPU - 9960)
HD4890 OC: P12645 (CPU - 17405, GPU - 11574)
HD4890 OC CFX: P17874 (CPU - 17358, GPU - 18053)


Remember, the 4870 was behind the GTX 260 192SP in Vantage, but still matched or beat in most of the game benches present. Now that 90 OCed is basically the same as 285, games should do quite well with it actually.

And of course, price. 285 is 14xx IIRC, 4890 is 1090 (and lower), 11xx for the 900Mhz OC model.

I expect 950 to be doable with the majority of the cards since the OC ed is already 900.
