Radeon HD 4830 Gaming Performance

AMD has prepared a slide on the Radeon HD 4830 performance vs the GeForce 9800 GT with 6 games benchmarks. No words on the system configuration or drivers used for these tests. AMD is banking heavily on this card to outperform and to outsell the GeForce 9800 GT at the same price point. In another slide, it stated that the Radeon HD 4830 series delivers up to 1.6x the performance per watt of AMD’s previous generation GPUs. 6.73 GigaFLOPS per Watt vs 4.10 GigaFLOPS per Watt for the HD 3850.

Naked Radeon 4350 pictured

RV710 based

We told you that next week, last days of Q3 2008, ATI plans to launch Radeon HD 4350 card. This card is based on 80 Shader powered RV710 chip.The die as you can see looks really small.


It will draw up to 25W and it will make the card very attractive for HTPC market and most of the cards will be passive. The card comes with DVI and VGA out and it will be extremely cheap. The card has a fan connector but most of the cards will come as the passive ones as moving parts such as fans tend to break after some time.

The card has 1024MB memory and it supports fancy features such is automatic overclocking called overdrive. On quad core 3.0GHz system it can score respectably 5400 points in 3Dvantage. This is how the card looks.

no co uz niesu nejake testy na 4830?

[crux2005]

o ~10% slabšia ako HD 4850 a super pomer cena/výkon...

WOW,prebehol som 14stran kym mi doslo ze ta lepsia cervenou vyznacena karta v grafoch nie je 4850

crux2005: co hovoris na teoriu RV790@12 SIMDs, ak by sa vyhodil sideport?

[crux2005]

12 SIMDs nevidím ako niečo nereálne a sideport je aj tak viac-menej zbytočný

RV775XT - odpoveď ATi na GeForce GTX285?

[crux2005]

minimálne špecifikácie nedávajú zmysel

48TMUs by znamenalo 12 RV770 clusterov, ale počet SPs - 840 značí niečo iné - polovičný cluster - teda 10,5 clusterov
+ tá 1400MHz ako frekvencia pamäte ...

[fobos]

podla mna to bude mat 960SPs , teda ten pocet povodne spajany s RV870 (ktora bude mat podla mna aspon dvojnasobok oproti RV770, nakolko s 960timi by to bol po vykonovej stranke shit)

Co sa tyka tych frekvencii, to je moc tych 900MHz, vidim to tak na 800-825 za predpokladu ze sa pocet klustorv bude ozaj zvysovat , sak to by zralo ako krava to jadro keby to ma dajme tomu 960 shaderov beziacich na 900MHz

[crux2005]

1.Q 2009 = RV7x0 refresh s vyššími frekvenciami
2.Q 2009 = RV8x0@40nm
4.Q 2009 = D3D11

a prvý kvartál nie je len január...

btw: o 27% vyššie pracovné frekvencie nie sú len "mierny tuning" jadra -> ergo, nereálne na rovnakom výrobnom procese

[marfan]

no to ak sa budútie jadrá ešte taktnúť tak to bude na to jadro asi maximum čo mohly spraviť

[qmoxx]

no zatial sa vsade pise ze prvy cip ktory AMD-ATI vida na 40nm je RV740tka ktora by vo svojej podstate mala byt cenovo pod 100 dolarov (teda cenou medzi sucastnou 4830-4670 , ale vykonom medzi 4830 a 4850.

K jadru samotnemu sa uvadza ze ze ma obsahovat :
640 sp
32TMU
16ROP
do 75 Watt bez pridavneho napajania
pamate niektory pisu : GDDR 5 ... GDDR 4 , GDDR 3 (asi aby si si mohol vybrat )
zbernica : 128bit /256 bit ( nasiel som obe alternativy , 128bit je pravdepodobnejsia )

Tato karta ma byt stale 10.1 a z specifikaci aj napriek tomu oznaceniu mi to prjde ze az na tu zbernicu to ma skor blizsie k 4830 ako 4670.
