[WCCF] AMD Bulldozer (Zambezi-FX) CPU Performance Exposed, Beats i7 2600K in CineBenc - Page 18  

post #171 of 227
^The whole point of the modules thing is not the core count, but a physical implementation of Intel's HT.

Windows treats the 2600k as an octacore, as it does with the 8130P. That is the point.

How the actual CPU is made, that is barely relevant. cinebench uses the eight available threads in both CPUs, no matter if they're physical or virtual.

yes but I dont see how this relevant to my calculation?
While HT boosts overall performance by roughly 18% you get almost full scaling with bulldozer int cores (said to be between 80-90%) so my calculation is somewhat accurate with a small offset of course; at least accurate enough to say that this is in no way the 8-core bulldozer unless it's running with significantly lowered clocks.

Same calc with modules:
7,37 / 4 = 1,84 (BD 4-module, 8-core)
7,37 / 3 = 2,46 (BD 3-module, 6-core)
5,9 / 3 = 1,97 (1100T with 2 cores)

So I think its still more reasonable that this is the 6 core considering the fact that a module is said to be faster than 2 thuban cores.

I like to see some more floating point benchmarks because the two modules per core of the BD is only int related. The HT technology is int and floating point so big change the Intel chips are kicking a** there. But I can be wrong of course.

I agree with that part. if that was a true octacore it would have similar per-core performance as an Athlon64.

I tend to favor AMD so obviously i hope BD comes out and kicks ass.. but i've got a gameplan for both chances:

BD rocks: Save some $$ and build a new system around BD enhanced or something further down the road

BD is "mehhh": sell off my 940BE, and 4870CF. buy 1090t, clock it @ 4ghz,a 6970, and another 4Gb of ram.. as games evolve and become more CPU intensive, they will also probably begin to take advantage of the 6 cores so that the CPU won't bottleneck for a LONG time... and when I see fit, just upgrade PSU and throw another 6970..

in fact this second plan sounds so awesome to me that BD has to be imba enough to make me change my mind

If you're interested in a cheap 1090t, check my sig. $160 and does 4.126GHZ on 1.45v.


OT: I think having huge arguments over Thuban, BD SB etc is a huge waste of time when BD is coming out out in 2 weeks.

I hope AMD is at least equivalent to the SB. If it comes out that way (or greater in speed) then the price war begins. Intel can stop raping you for the performance.

[I fully understand that Intel is often faster, but it shouldn't been that they can have such a high dollar to performance ratio]

If an 8 Core CPU doesn't beat a 4 Core Hyper Threaded CPU, then AMD would have a serious problem on their hands, and they know this man!

Its looking more and more like the wind is being taken out of BD's sails. Shame....
post #180 of 227
Best case scenario is that it dominates SB, resulting in intel having to pick up their game with IB, Resulting in it crushing BD, resulting in amd having to pick up their game with BD-E, And so-on, and so-on
