AMD K10 Agena + Barcelona + Kuma

[fobos]

tak no ved uvidime 10 septembra, nech uz konecne viem co si mam kupit!

ty si ides kupovat nejaky serverik?

Ja by som na tom nic divne nevidel (K8 serverove CPU si si mohol dat normalne do desktopu), ale tu je jeden hacik. Barcelona je do socketu F, teda ak ma AM2 dosku tak ma smolu

no vidis.. socket F je 2CPU/4CPU, a agena na AM2+ budu vydane v decembri, dostupnost na jar

- Gaming performance is much improved with Barcelona over K8, this is most likely a result of the improvements to the SSE engine and the wider front end of the core.

- Encoding performance is improved (again SSE128 rearing its head), but 3dsmax saw an unexpectedly large performance improvement.

- With a 10 - 15% increase in performance on average, Phenom should be more competitive than K8 was on the desktop (as expected).

IBM posts LS-DYNA benchmark results for quad-core x3455 server

The x3455 server achieved an elapsed time of 31,526 seconds, which is better than the 32,578 seconds of elapsed time achieved by a single-node 8-core blade system using the Quad-Core Intel® Xeon® X5355 processor at 2.66GHz. (1) Improved LS-DYNA performance can result in quicker simulations by industry users, which in turn can result in delivery of better and safer products to the marketplace in less time

The new Barcelona-based quad-core Opterons bring major performance gains over their dual-core predecessors while fitting comfortably into the same power and thermal envelopes. Doubling the number of CPU cores will take you a long way in the server/workstation space, where the usage models tend to involve explicitly parallel workloads. The new Opterons also bring improved clock-for-clock performance in some cases, most notably with SSE-intensive applications like the Folding@Home Gromacs core. However, Barcelona's gains in performance per clock aren't quite what we expected, especially in floating-point-intensive applications like 3D rendering, where it looks for all the world like a quad-core K8. As a result, Barcelona is sometimes faster, sometimes slower, and oftentimes the equal of Intel's Core microarchitecture, MHz for MHz. Given the current clock speed situation, that's a tough reality.



That said, new processor microarchitectures often scale quite well with clock speed, and our sneak peek at the 2.5GHz Opteron 2360 SE suggests Barcelona might be that way. Still, one can't help but wonder whether AMD did the right thing with its L3 cache. That cache's roughly 20ns access latency erases the Opteron's lifelong advantage in memory access latencies, yet it nets an effective total cache size just over half that of the current Xeon's. Since the L3 cache is clocked at the same speed as the memory controller, raising that memory controller's clock speed should be a priority for AMD. This particular issue may be more of a concern in desktops and workstations than in servers, however, given the usage models involved.

Tieto masazne obrazky mam tak rad... nikde ale nie je vykon tych CPU na frekvenciach okolo 3GHz, pretoze to proste nezvladaju... a pre Xeony to nie je problem... cize pre max. vykon jedine Intel

proste dalsi suboj - maly prd od AMD vs nervovy plyn od Intelu

Zasa dalsi duchaplny prispevok zaryteho Intelistu :roll: Barcelona vyssich taktov dosiahne , to sa neboj. Ja sobne si myslim ze tych 2GHz na nativne 4 jadrovy procesor nie je sice nejak extra ale ani najmenej. A keby tu Barcelona nebola a ani K8 tak si C2D kupujes od 15k nahor ...
