Page 1 of 4  From the very beginning of computer epoch, opinion was that parallelization and everything connected to computers needs to be scaled to the second power, although it doesn’t matter if you have 1, 2 or even 73 cores. In any case, everything will work properly, unless we are talking about some old version of synthetic benchmark programs that doesn’t recognize processor with odd number of processors. If one worker will do the job for 24h, two will do for 12h and for three workers you can guess by yourself. This analogy goes for multi-thread software which can recognize multi-core processors.
Has this one “the bug”?
New AMD K10 architecture is what is all about here. We have explained this technology very thorough, so we won’t waste your time on this subject here again. Phenom 8750 belongs to so called xx50 series, which means that this is new B3 revision that doesn’t have infamous TLB bug. This actually means that processor will work on full speed on any motherboard and only because TLB patch will not be active. Some motherboards simply don’t have in their BIOS possibility to turn off this patch and that’s the reason why “bug-free” CPU is more than welcomed.
Performances
During the test, triple-core processor has showed as more efficient solution than duo-core CPU, even at significantly higher frequencies, for rendering and video compression. That is quite understandable because these sorts of applications have almost ideal scalability with increasing number of cores. We must underline that scaling from 2 to 3 cores is, in percentage, much better than from 3 to 4, so it comes out that, in real conditions, this X3 hybrid isn’t much slower from its high-end brothers. Phenom 8750 is able to pull out practically the same FPS in games like quad-core 9750, and that’s because games are limited by graphics card and because just few games on the market, at this point, have support for CPU’s with more than two cores.
Overclock
B3 revision has far better overclock potential than its predecessor B2. Unfortunately, AMD will not launch Phenom Triple-Core Black Edition, so our hopes for easy overclocking, using just simple multiplier change, fell to the ground. Good overclock of 8750 requires excellent motherboard with “overclock pedigree”. Did someone whisper DFI?! Well, of course, that chipper Biostar boards with AMD 770 chipset will do, and also will do new series of nForce 750a based motherboards and, of course, unavoidable Asus Crosshair Formula II 780a. Even users with little overclocking skills and some courage, that have these motherboards, can easily pull out the maximum from AMD Phenom X3 Triple-Core 8750. We managed to push frequencies up to 3 GHz for tested sample and if you low frequencies for memory controller it is possible to get even 3.1-3.2 GHz with default voltage for 65nm CPU’s. You will also need, for this kind of overclock, proper cooler based on heatpipe technology.
