Apparently if you are looking to overclock, ivy bridge retail stepping is a much hotter chip. What this means is that you will not hit as high overclocks upgrading from a sandy bridge 2700k to the 3770k. The difference in overclockability outweighs the IPC increase, and therefore these two chips are nearly equivalent at maximum overclock.
The bottom line is, unless your planning on running stock, or to overclock with L2N, these chips are a BIG side-grade from sandy bridge. What makes this worse is the price of the new ivybridge chips will be in the 350+ USD dollar range, which for only a few more dollars will get you a significantly more powerful and overclockable i7 3930k by then.
Remember how the i7 2600k smoked the 980x in many tests? Dont expect this with ivy bridge against current E series processors. Ivy bridge will be a worse jump from sandy bridge, than any intel CPU jump in history.
In Pro-Intel OBR's own words, "Ivy Bridge E1 are total shit! Do not buy them! "

ReplyDeletebut seriously, 22nm is new and intel really didn't seem to have mastered it (neither has TSMC mastered 28nm), vishera seems to be good, remember anything >= 2.0 from AMD is excellent
if AMD vishera is as good as I expect, AMD might have a great chance, I expect 8-cores to be as good as mid-range IVB-E and quite better than IVB, 6-cores would be nearly as good as IVB i7s and 4-cores would be nearly as good as i3s, all that at gaming, but at computing, server stuff, HPC.... it would easily outperform intel IVB(-E)
remember that's all expectations
everyone wishes AMD would be a serious competitor to intel
BTW (when will)/(will) linux/power benches come out?
Even as an abid amd fan I highly doubt your performance predictions are correct. I suspect an 8 core vishera processor will be roughly 25 to 35 percent better per core than first gen bulldozer, with scaling increase of roughly 10 percent (amd focusing on heterogeneous processing), and 5 percent better oc range, so a 5 ghz vishera 8 core processor will perform roughly equivilent to a 4.3 - 4.5 ghz 3960x, while for comparison sake a 4.8 ghz fx 8150 performs roughly equivilent as a 3.3 ghz 3960x. 6 core vishera parts at 5 ghz will only perform equivilent to an 1100t at around 4.4-4.5 ghz. Of course this is just a guess, but we will see soon enough. A 6 core 12 threaded ivy bridge e processor will perform better than an 8 core vishera processor, but will cost significantly more. The performance gap between intel and amd will most definitly shrink in the next gen of desktop processors.
ReplyDeleteremember the HD 2000 (AMD) graphics cards? well they were the first graphics cards by AMD (after buying ATi), they sucked but amd did follow them with more competitive offerings like what we see now : the HD 7900 series, extremely competitive
Deletei didn't say 8-cores would beat intel's 6-cores but they should beat their 4-cores extreme editions, the 6-cores would be a little less than normal i7/i5 IVBs (like how phenom II were once they came out) and 4-cores would be a little like i3s
actually AMD FX-4100 is only a little less than intel SB i3s, see tomshardware.com
since TVB is merely a die shrink, it shouldn't be tha of an improvement to SB but vishera is a new architecture, that's why i have high expectations for it
