AMD Bulldozer

Bomo vidli, upam da čimprej.

Je Fr4nc naredil GFlops test?
http://www.softpedia.com/get/System/Ben...

Sem naredil eno primerjavo med Vishero okoli 45(GFlops), Core i5 okoli 70G(Flops) in Epiphany-IV 64-core 28nm naj bil 100(GFlops) to stane dev.plata okoli 100€.

No tole me je zanimalo...

"A key reason for the unmatched efficiency of the Epiphany-IV chips comes from early access to Globalfoundries leading-edge 28nm SLP technology. The industry to date has been challenged by the 28nm process node, but the Epiphany chip was able to exceed expectations in terms of performance, the two companies said."

Kdaj bo kaj iz tega je vprašanje, če bo cela plata stala 100€ in bila močna kot Core i5, za 5x manjšo ceno, potem je to to.

V bistvu gre tukaj za FPU, ki ga ARM potrebuje.

The Epiphany IV chip includes 64 independent high-performance RISC cores on a single chip that operates at up to 800MHz, effectively offering over 50GHz of achievable programmable performance...

whatever. scaling na njih ne vpliva?

Kakšen AMDjev marketing ?

Tole je zasnovala Adapteva, GloFo pa zapekel v silicij. Veze nima z AMDjem.

Pojma nimam.

V bistvu ni tako. Stroja nista primerljiva.

Vishera je klasičen CPU, tole je bolj podobno polju shaderjev.

Stvar je rezultat prej premišljenih pazljivo zastavljenih kompromisov.

Kar pomeni, da tole niti slučajno ni nek splošen multicore, uporaben za širok spekter problemov.

Zelo zanimiva zadeva ( potencialno) ampak ni v isti dirki kot x86 stroji.

AMD slashes desktop CPU prices

cca. 10-19% pocenitev.

Richland APU je pred vrati.

Taka cena ob splavitvi...uf

Virtual memory? kaj je to Brane pomagi.

AMD's master plan partially revealed

Zanimivo napisan članek, glede na omejene informacije...

Sem že mislu vprašat o CPU nasledniku Piledriverja, pa sem našel svež odgovor:

Centurion

Saj. Ampak bilo je rečeno, da bo zadnji CPU Piledriver, naprej pa samo APUji.

Potem je bila novička o Steamroller Opteronih, sedaj pa še o CPUjih za navadne mašine.
Zdaj vemo, da bodo na voljo vsaj high-end zadeve.

Zabavno tole ... brat, kako novinarji sploh ne dojamejo, za kaj se zares gre. HPC svet že vse od pojava GPUjev zahteva skupni pomnilnik, sedaj ga bo končno tudi dobil :)

Pa še nekaj špekulacij: šušlja se že, da bo naslednji amdjev korak zamenjava x86 jedr z arm jedri v skupnem cpu+gpu čipu. Na misel mi je prišlo pa še nekaj drugega - današnji ati gpuji so vliw zadeve, da? Se še spomnite Transmete in njihovih Crusoe vliw procesorjev, ki so prevajali x86 ukaze v interne vliw? Kdo si sedaj lasti te patente? Se mi zdi, da bi se dalo na tej podlagi skuhati nekaj zanimivih izdelkov ...

Lastnik Transmetinih patentov je nek patent troll (Intellectual Ventures).

Choosing a Gaming CPU: Single + Multi-GPU at 1440p, April 2013

Šibajo v pravo smer.

Samo že Richland zdaj zdaj izdajo pa bo čez 4 dolarje.

Samo bo še part.2 članek, model bo testiral še FX-4xxx in FX-6xxx in ostale, ki manjkajo. Mi je pa všeč tole:

A CPU for Single GPU Gaming: A8-5600K + Core Parking updates

If I were gaming today on a single GPU, the A8-5600K (or non-K equivalent) would strike me as a price competitive choice for frame rates, as long as you are not a big Civilization V player and don't mind the single threaded performance. The A8-5600K scores within a percentage point or two across the board in single GPU frame rates with both a HD7970 and a GTX580, as well as feels the same in the OS as an equivalent Intel CPU. The A8-5600K will also overclock a little, giving a boost, and comes in at a stout $110, meaning that some of those $$$ can go towards a beefier GPU or an SSD. The only downside is if you are planning some heavy OS work - if the software is Piledriver-aware all might be well, although most processing is not, and perhaps an i3-3225 or FX-8350 might be worth a look.

A CPU for Dual GPU Gaming: i5-2500K or FX-8350

Looking back through the results, moving to a dual GPU setup obviously has some issues. Various AMD platforms are not certified for dual NVIDIA cards for example, meaning while they may excel for AMD, you cannot recommend them for Team Green. There is also the dilemma that while in certain games you can be fairly GPU limited (Metro 2033, Sleeping Dogs), there are others were having the CPU horsepower can double the frame rate (Civilization V).

After the overview, my recommendation for dual GPU gaming comes in at the feet of the i5-2500K. This recommendation may seem odd - these chips are not the latest from Intel, but chances are that pre-owned they will be hitting a nice price point, especially if/when people move over to Haswell. If you were buying new, the obvious answer would be looking at an i5-3570K on Ivy Bridge rather than the 2500K, so consider this suggestion a minimum CPU recommendation.

On the AMD side, the FX-8350 puts up a good show across most of the benchmarks, but falls spectacularly in Civilization V. If this is not the game you are aiming for and want to invest AMD, then the FX-8350 is a good choice for dual GPU gaming.

A CPU for Tri-GPU Gaming: i7-3770K with an x8/x4/x4 (AMD) or PLX (NVIDIA) motherboard

By moving up in GPU power we also have to boost the CPU power in order to see the best scaling at 1440p. It might be a sad thing to hear but the only CPU in our testing that provides the top frame rates at this level is the top line Ivy Bridge model. For a comparison point, the Sandy Bridge-E 6-core results were often very similar, but the price jump to such as setup is prohibitive to all but the most sturdy of wallets.

As noted in the introduction, using 3-way on NVIDIA with Ivy Bridge will require a PLX motherboard in order to get enough lanes to satisfy the SLI requirement of x8 minimum per CPU. This also raises the bar in terms of price, as PLX motherboards start around the $280 mark. For a 3-way AMD setup, an x8/x4/x4 enabled motherboard performs similarly to a PLX enabled one, and ahead of the slightly crippled x8/x8 + x4 variations. However investing in a PLX board would help moving to a 4-way setup should that be your intended goal. In either scenario, at stock clocks, the i7-3770K is the processor of choice from our testing suite.

A CPU for Quad-GPU Gaming: i7-3770K with a PLX motherboard

A four-way GPU configuration is for those insane few users that have both the money and the physical requirement for pixel power. We are all aware of the law of diminishing returns, and more often than not adding that fourth GPU is taking the biscuit for most resolutions. Despite this, even at 1440p, we see awesome scaling in games like Sleeping Dogs (+73% of a single card moving from three to four cards) and more recently I have seen that four-way GTX680s help give BF3 in Ultra settings a healthy 35 FPS minimum on a 4K monitor. So while four-way setups are insane, there is clearly a usage scenario where it matters to have card number four.

Our testing was pretty clear as to what CPUs are needed at 1440p with fairly powerful GPUs. While the i7-2600K was nearly there in all our benchmarks, only two sets of CPUs made sure of the highest frame rates - the i7-3770K and any six-core Sandy Bridge-E. As mentioned in the three-way conclusion, the price barrier to SB-E is a big step for most users (even if they are splashing out $1500+ on four big cards), giving the nod to an Ivy Bridge configuration. Of course that i7-3770K CPU will have to be paired with a PLX enabled motherboard as well.

One could argue that with overclocking the i7-2600K could come into play, and I don't doubt that is the case. People building three and four way GPU monsters are more than likely to run extra cooling and overclock. Unfortunately that adds plenty of variables and extra testing which will have to be made at a later date. For now our recommendation at stock, for 4-way at 1440p, is an i7-3770K CPU.

Ubistvu je res. Marketing jih jebe. Od njih ni nič reklam, še na slovenskih medijih imaš na vsake kvartale eno reklamo za Intel.

Posledica, da ima AMD foo marketing, je vidna recimo v oni temi, kjer nekdo sprašuje za amd konfiguracijo, pa mu folk takoj začne "vzami raje intel" iz razlogov, ki so primarno marketinške narave.

Videti je, da je novo vodstvo AMDja to prepoznalo in kot novo smer najavilo izdelavo semicustom rešitev za specifične stranke. V takih zgodbah se marketing dela popolnoma drugače in se ti dejansko ni treba za mindset mularije borit.

Napačno razmišlanje.

A res, ravno v tistem arstechnica članku avtor omeni, kako je vplival Sandersov odnos do zapravljanja denarja in obsesije pri (prehitrih) odločitvah, kot je bila tista s fabrikami. In to je samo ena zadeva, ena odločitev, ki jo je naredil kot šefe v mnogo letih...

ATI se je takrat prodal za neverjetne denarje, ni pa jasno kaj je AMD s tem dobil.

ATI ni imel svoje proizvodnje. Čiperaj je naročal pri Foundryjih, tako kot ga koneckoncev lahko ti ali pa jaz.

Večina "vrednosti" je bila v know-hhowu, patentih in SW, z ničemer od tega si pa AMD ni imel kaj pomagati.

Njihov plan je bil integracija v APU, tam je bil pa ATI bos, ravno tako kot kdorkoli drug.

To, kar danes oglašujejo kot APU bi komot lahko imeli v času prvih Phenomov recimo.

Po eni varianti bi se recimo lahko zmenili s kakim ATIjem, da jim zdilajo nov model čipa s HT namesto PCIe vmesnikom in tega bi pač lahko vdelali na novo podnožje, ravno kot to počnejo danes z Opteroni. S CPUjem bi bil povezan prek HT linka in to je to. Par DDR-3 čipov na plato ali še bolje v podnožje in piči miško.

Po drugi varianti bi pa to lahko naredili sami. Karkoli bi tako ustvarili, bi bilo lahko komot bolje kot običajna integrirana rešitev.

Ja sam a ni bolje, da je stvar on-die, kot pa nekje zalotana na platki ?
sj amd je meu te "apuje" že pred atijem zalotane v čipset...
