AMD/ATi R(V)8x0

zeby kvoli extreme OC??

pot pre kartu s pamatami aj z druhej strany by bol dost zlozity (spojil som si to s jeho avatarom)

[Shatterhand]

Staci pot len na jadro...a pri LN2 je okolie jadra, a teda PCB na okoli doslova zmrznute, cize netreba tam nic specialne.

[beardie]

Extreme OC snad nebude robit na mainstream karte...

To be precise it's 2nd Generation TeraScale Engine.

Cypress info kits have been sent out so expect more leaks with various marketingterms like Enhanced UVD2 (which support hardware acceleration decode of dual 1080p HD video streams) and ATi Eyefinity.

Oh and marketingnames have indeed been decided.

výkon Cypress karty je trochu pod GeForce GTX 295

[Zoltan Balaton]

Trochu budem asi out,ale mam to chapat tak ze nazov Radeon skonci a budu nazvy podla vykonnosti? (Cypress,Juniper,Redwood, Cedar, Hemlock)

[beardie]

to su len kodove nazvy, ani nehalem sa nepouziva standardne, miesto toho je Core i7

[Shatterhand]

Proste aj graficke cipy maju svoje "kodove" oznacenia.

[Zoltan Balaton]

ake je teda kodove oznacenie R770 ?

[M1ch4l]

Codename(s):

Wekiva
Makedon (RV770)
Trojan (RV770)
Spartan (R700)

takze P17000 priblizne sedi a malo by sediet aj 1600 SP

btw: je zaujímavé, že vždy keď som niečo počul o "RV870", tak sa zvýšila oproti posledným informáciám jeho veľkosť jadra. Pravdepodobne to súvisí ako v prípade RV770 s vývojom. A ten PDF dokument čo mám - Cypress je v ňom nazvaný Radeon 7xx, je fake.

AMD has informed their partners that their upcoming DX11 Cypress cards will be known as Radeon HD 5800 series. Cypress XT is Radeon HD 5870 while Cypress PRO is Radeon HD 5850. The key features of these DX11 cards are :

• 1GB GDDR5 memory
• ATI Eyefinity technology with support for up to three displays
• ATI Stream technology,
• Designed for DirectCompute 5.0 and OpenCL
• Accelerated Video Transcoding (AVT)
• Compliant with DirectX® 11 and earlier revisions
• Supports OpenGL 3.1
• ATI CrossFireX™ multi-GPU support for highly scalable performance6
• ATI Avivo™ HD video and display technology
• Dynamic power management with ATI PowerPlay™ technology
• DL-DVI, DL-DVI, DisplayPort, HDMI
• PCI Express® 2.0 support

The launch will take place in September and retail availability in October, same time as Windows 7 launch. More details later.

- display outputs: DVI/DVI/DP or DVI/HDMI/DP. ATi Eyefinity support as of Cat 9.10 (8.66). Converter is included.
- "Feel the power of more than 2 teraFLOPS plowing through the most demanding games."
- "Get up to 1.8X of a graphics performance boost with ATI CrossFireX™ technology in dual mode."

Zaujímavý je imho termín uvedenia - 24. septembra, teda 6 dní pre nV GPU summitom. Keď nVidia na ňom nič neoznámi, tak sa AMD/ATi zbytočne ponáhľala, lebo prognózy dostupnosti sú zatiaľ biedne -> stred októbra.

Zapojenie 3 monitorov je fajn.

Cypress XT a PRO ma mat "more than 2TFLOPs"? Vyzera to ze ano, lebo tie frekvencie pri 1600SPs by boli pre vykonnejsiu verziu nizke, ci nie?

So, 2 teraflops can be achieved with:

1200 SP at 833 MHz
1600 SP at 625 MHz
2000 SP at 500 MHz

[beardie]

4850 mala 1 TF a tiez sa hovorilo o jadre RV770, ze je prve, ktore dosiahne 1 TF
mozno "nad 2 TF" plati pre 5850 a 5870 bude zase o par 100 GF vyssie

[yesper]

Takze teoreticky by sa to mohlo pohybovat medzi:
HD5850 - 1600 SP @ 650 ~ 700 MHz : 2,080 ~ 2,240TFLOPs
HD5870 - 1600 SP @ 800 ~ 850 MHz : 2,560 ~ 2,720TFLOPs

Skor tie nizsie hodnoty
