AMD/ATi R(V)8x0

[M1ch4l]

netrufam si odhadnut cenu 5850 presne, ale tak $199 az $239 by bolo realne

[yesper]

či konečne niečo vylepšili na AF

Takze nieco mozno aj bude.

Did I already mention that a new reference in texture quality is coming towards us soon for all those IQ freaks out there?

som zvedavý

pise sa nieco o ujasneni na PCT fore, zobrali to z extremesystems,

Architecture explained by a newb:
Dual core / MCM: This generation supports a new "hard" method of dual gpu rendering that differs from previous Crossfire implementation that we see R800 and in rv870 crossfire situations. The chinese translation is "dual core" or split frame hardware- Has something to do with the way the shaders/alus etc operates inside an individual gpu (a method of simultaneous operations in the hardware, similar to dual core, yet not actually two dies in one package ala MCM). Perhaps there is no more real-time compiler in the driver and its all handled on the hardware level by the scheduler. Because the core of the chip is so modular & scalable with certain areas sharing parts of the die (ROPS + Memory controller logic), you are able to divide the specs in half (1600/256/80/32 to 800/128/40/16) and have two parts (rv870/rv830) and rv870 appears as two rv830's, yet it is still only one die. Hence term "dual-core" - more like "modular". Some people think, yes, but all GPUs are multi-core because each of the shaders is like a core by itself. Well, here we are dealing with two large arrays of 800 shaders, along with other standalone logic that communicates with either one of the two identical arrays. More specifically, one Rv870 die is composed of two Rv830-like 160x5 clusters/shader arrays (like two current-gen revamped rv770's in one die) sharing certain features, but connected via "internal crossfire" working in unison and the entire design is a continuation of R600 architecture. It is load balanced, efficient, and requires no crossfire software optimization (because it is hardware level communication); it works via SFR 8*8-32*32, and is bandwidth intensive. The board is using next-gen 5ghz Gddr5 to provide the required bandwidth. So, apparently they've slapped together two 40nm rv770's... so it's easy to see where "dual-core" confusion comes from. Cypress is like a 40nm 4890x2 in one die! -So, it is like a "native dual core" CPU. Now that specs are known for Cypress & Juniper (rv870 & rv830) you can expect that the remaining parts Cedar & Redwood (rv840 & rv810) are 3/4 Cypress & 1/4 Cypress respectively, and that Hemlock (r800) is 2 x Cypress in the same fashion as the HD4870x2 on a single PCB. So, Cypress is like a larabee, except that it uses 2 rv770 cores, whereas larabee is using several P54C cores. (Even though this isn't an actual rv870 die shot, rather an artist's rendition posted earlier - when you do see an actual one, it will look more like the first two images ie. a symmetrical reflection of two identical core areas over a center axis, rather than the third picture - which is an actual die shot of rv770. Notice in the 3rd pic that the rv770 is asymmetrical by design, not resembling a dual core architecture.)

tak vraj DX11 in action http://www.youtube.com/watch?v=zZAwniLT22U" onclick="window.open(this.href);return false;

no vidiet tam z hry prakticky prd, takze na nieco lepsie si budeme musiet pockat a z toho, co vidiet, sa mi nechce verit, ze ide o DX11 zabery

[crux2005]

tú citovanú časť som už pred ~3 stranami postol
a to video je imho pravé, avšak nemusia tam byť zábery so zapnutým D3D 11

[M1ch4l]

video je asi prave, ale D3D11 tam podla mna nebude

v najblizsich dnoch/tyzdnoch to vyjde na PS3 a X360, na PC vyjde v decembri
pochybujem o tom, ze by uz mali funkcnu DX11 verziu hry....myslim si, ze su momentalne v pre-alpha alebo alpha stage vyvoja a este to nemaju uplne implementovane

nech sa aj pokrajam, nemozem tu citovanu cast najst, ale kaslat na to...toto je dost zrozumitelny text a aj by som tomu veril

More Details about ATi Eyefinity Technology

[yesper]

Len doplnim, ze v clanku je opat zmienka o novej metode AF.

...it supports a new anisotropic filtering method too...

Uz nech je 10.9.

[crux2005]

10.9. sa možno dočkáš nejakého leaku

Fuad nieco vypotil, ale moc sa mi to nepozdava

60% narast vykonu je dost malo, to by potom RV870 malo len tak 1200 SP, plus 60% narast hrubeho vykonu by daval menej ako 2TFLOPS

[yesper]

Toto moze platit aj pre HD5850, podla mna to malo nie je. Aritmeticky vykon a realny sa porovnavat nedaju. Ani 1200SPs to nepotvrdzuje.

[crux2005]

aritmetický výkon sa ale neodráža 1:1 vo výkone hier a aj s 1280SPs sa dá dosiahnuť >2TFLOP/s...
btw: moje puzzle je to, čo no-X už dlhšie zverejňuje, lebo som mu ho prezradil

[M1ch4l]

a tvoje puzzle je pravda? lebo on dost vela hovoril o 1280 SPs, co je mozne, ale je to imo skarede cislo

ale kaslat na to, sak sa dozvieme, co a ako
na 750MHz s 1280SPs (presne 60% viac ako 800) je 1.94 TFLOPS ci ako

to, ze navysenie vypoctoveho vykonu nezodpoveda navyseniu vykonu v hrach, mi je jasne, 60% narast je celkom slusny, ale mohlo byt viac, pasovalo by to s P10 000 (4870) a udajnymi P 16 000

btw kedy dame to cod4?

[fobos]

M1ch4l: ak sa ti máli 60%, tak si potom prečítaj dnešnú "zaručenú" info o HD5870 od OBRa

[M1ch4l]

ta jeho novinka je kopa zvastov, ktore nejdu dohromady
takt ako 4890 a 2x tolko SPs a 20-30% vyssi vykon? s tak vypiplanou architekturou?

tych 60% je dost, ale cakal som viac, no podla mna je to zatial najrealnejsie cislo (konkretne v porovnani 5870 a 4870)
