http://www.anandtech.com/show/11002/...cture-teaser/1

Schimbarea cea mai importanta pe care o aduce VEGA(in afara de noul Memory System) e descrisa mai jos:
"ROPs & Rasterizers: Binning for the Win(ning)
We’ll suitably round-out our overview of AMD’s Vega teaser with a look at the front and back-ends of the GPU architecture. While AMD has clearly put quite a bit of effort into the shader core, shader engines, and memory, they have not ignored the rasterizers at the front-end or the ROPs at the back-end. In fact this could be one of the most important changes to the architecture from an efficiency standpoint.

Back in August, our pal David Kanter discovered one of the important ingredients of the secret sauce that is NVIDIA’s efficiency optimizations. As it turns out, NVIDIA has been doing tile based rasterization and binning since Maxwell, and that this was likely one of the big reasons Maxwell’s efficiency increased by so much. Though NVIDIA still refuses to comment on the matter, from what we can ascertain, breaking up a scene into tiles has allowed NVIDIA to keep a lot more traffic on-chip, which saves memory bandwidth, but also cuts down on very expensive accesses to VRAM.
For Vega, AMD will be doing something similar. The architecture will add support for what AMD calls the Draw Stream Binning Rasterizer, which true to its name, will give Vega the ability to bin polygons by tile. By doing so, AMD will cut down on the amount of memory accesses by working with smaller tiles that can stay-on chip. This will also allow AMD to do a better job of culling hidden pixels, keeping them from making it to the pixel shaders and consuming resources there.

As we have almost no detail on how AMD or NVIDIA are doing tiling and binning, it’s impossible to say with any degree of certainty just how close their implementations are, so I’ll refrain from any speculation on which might be better. But I’m not going to be too surprised if in the future we find out both implementations are quite similar. The important thing to take away from this right now is that AMD is following a very similar path to where we think NVIDIA captured some of their greatest efficiency gains on Maxwell, and that in turn bodes well for Vega.

Meanwhile, on the ROP side of matters, besides baking in the necessary support for the aforementioned binning technology, AMD is also making one other change to cut down on the amount of data that has to go off-chip to VRAM. AMD has significantly reworked how the ROPs (or as they like to call them, the Render Back-Ends) interact with their L2 cache. Starting with Vega, the ROPs are now clients of the L2 cache rather than the memory controller, allowing them to better and more directly use the relatively spacious L2 cache.

Si asta e tot. NVidia n-a anuntat 1080Ti iar de la AMD tot ce primim e un preview la Vega.

CES 2017 s-a terminat din punctul meu de vedere.
Let's move along...

Ciudat! Ori NVidia i-a suparat cu ceva (greu de crezut din moment ce EVGA au scos doar placi bazate pe chipset Nvidia, ori vor mai mult ...) Poate pe VEGA , nu le mai iau foc placile video..........:P

EVGA este unul dintre cei mai mari integratori nVidia.
Si nu ar fi singurul care face si placi AMD si nVidia, nu cred ca le-ar scadea cota de vanzari pe nVidia daca adopta AMD, doar vor vinde si altceva, deci bani mai multi la tescherea.

Inclin sa nu dau crezare zvonului cu EVGA (pana la proba contrarie) dar am aflat ca Supermicro (https://www.supermicro.com/index_home.cfm) care avea la oferta numai Tesla si Xeon_Phi pana acum pentru servere si statii grafice va oferi incepand de anul asta solutii bazate pe Vega. Sper ca asta e o indicatie ca o fi ceva de capul noii arhitecturi de la AMD atunci cand o sa apara placi grafice bazate pe VEGA si la rafturi ( probabil nu mai dereme de luna Mai dupa cum se prezinta lucrurile acum...)

Si o chestie interesanta despre utilizarea VRAM din preview-ul la VEGA:

One of the most common misconceptions about GPU RAM allocation and the popular freeware utility GPU-Z is that GPU-Z is capable of telling you how much RAM the GPU is actually using. As we first covered in our tests of whether 4GB of RAM was enough for the Fury X, it is not. GPU-Z and all of the utilities that report VRAM usage under DirectX 11 cannot tell you how much RAM the GPU is actually utilizing because that information is not actually given by the DirectX 11 API. Instead, they report how much RAM has been allocated by the GPU, not whether the GPU is actually making any use of that VRAM. As the slide above shows, the gap between how much VRAM has been allocated and how much VRAM is actually in-use is quite significant, even in popular titles. The goal of AMD’s HBC + HBCC cluster is to allow the GPU to load and access data more efficiently.
https://www.extremetech.com/extreme/...codename-vega0

Asadar, una e ce raporteaza utilitarele gen GPU_Z si Afterburner in materie de consum de memorie video si alta e realitatea...

Cred ca asta e singurul joc in care amd testeaza placile video =)) culmea e ca nu joaca nici dracu acest joc, si nu e nici pe departe un joc cu cerinte deosebite.
Sa testeze tata in jocuri noi cu cerinte mult mai mari decat saracia asta de joc.

Eu zic ca gresesti!

http://www.geforce.com/whats-new/art...s-using-vulkan ...cam asa s-a lansat 1080!

si un 1080 overclockat in Doom 4K


Incep sa cred ca unii chiar sunt platiti de Nvidia! Trebuie sa iau si un produs musai!


Trezindu-ne... cred ca ar fi mai util sa privim lucrurile dintr-o perspectiva matura: impactul din buzunarul nostru in urma acestei lansari, indiferent de culoarea produsului achizitionat in final! Sansele ca impactul asupra pretului sa fie unul pozitiv sunt mari indiferent daca Vega bate sau nu 1080 in majoritatea titlurilor care conteaza!

Ar fi fost relevant un joc cu cerinte mai mari, nu neaparat directx11 sau 12. La directx12 sunt foarte multe probleme inca. Insa un bf1 consider ca era mult mai util decat *****ul asta de joc. E ca si cum am testa performanta placilor video in mario.
E un joc slab, pe care il poti juca lejer si pe o integrata. Nu intereseaza pe nimeni performanta in jocul acesta, intr-ucat e un joc pe moarte. Un joc gen tomb raider in directx 12 sau bf1 erau mult mai adecvate pentru a arata cu adevarat puterea placii video. Dar ce sa facem mizam pe aceeasi carte cu vesnicul doom.

DX11 e putin relevant, avand in vedere ca mai sunt pana la ~6 luni pana la lansarea vega. Cine o va cumpara, o va cumpara pentru jocurile viitoare ce vor aparea in urmatorii ~2 ani, intervalul la care se lanseaza placi video.
Cat despre jocurile DX11, sunt relevante doar jocurile populare online, gen wow ( banuiesc ca nu e dx12 ), nu alea DX11 care au avut vanzari primele ~2 luni si dupa care au fost uitate de lume, cu campanii de cateva ore single player sau multiplayer slab / inexistent pe care nu le mai joaca nici dracu.
Exemplu, nu ar interesa pe nimeni cum se comporta vega vs titan in crysis 3. Poate doar de curiozitate, dar atat.

Nu cred ca e greu sa tragem o concluzie! Vedem Vega depasind 1080, ba chiar in ton cu Titan XP dar nu asta conteaza!

Conteaza ca sunt sanse sa avem competitie si sa vedem niste preturi mai asezate! Mie chiar imi surade un 1070 la pe 16-17 mil! Sau mai sus niste preturi mai prietenoase!

Chestia cu DirectX 12 si Vulkan nu mai e asa tabu! Asa se spunea si la lansarea lui RX480...ca numai un titlu e si deh... si prin toamna erau vreo 6 titluri... care nu erau chiar atat de necunoscute!
