Performance Mandel FPU | Video transcoding
Mandel FPU test
The Mandel FPU benchmark measures double precision (also known as 64-bit) floating-point performance through the computation of several frames of the popular 'Mandelbrot' fractal. The code behind this benchmark method is written in Assembly, and it is extremely optimized for every popular AMD and Intel processor core variant by utilizing the appropriate x86 or SSE2 instruction set extension.
Now if you come from the Commodore 64 / Amiga era like me (Peek & Poke Commands FTW dude!), you can probably remember rendering Mandelbrot graphics, a mathematical formula that much like a paradox, never ends and thus is repetitive. Back in the 1990s it took me a full day to complete one Mandelbrot image. Amazing where we are right now as the same set of calculations can be done in a split second & even real-time.
The FPU Mandel test again is Hyper-Threaded, multi-processor (SMP) and multi-core aware.
MKV x.264 Video Transcoding
Movie encoding - x.264 is a free library for encoding H.264/MPEG-4 AVC video streams. Encoding/transcoding to that format is one of the most intensive tasks a processor can perform. As such this is probably the best test in the entire review. We encode a h.264 Dolby Digital 1080P trailer of 150 MB to Matroska x.264 with 5.1 channels AC3. It's compressed in such a way you can play it back with Haali media splitter and/or FFDSHOW codecs.
We use Handbrake software which is multi-core aware... the more processor cores it sees, the faster it can and will transcode. This software is also a perfect benchmark for CPU and memory testing.
The displayed number is the number of frames rendered per second averaged out over the encoding process. The higher the number, the faster the performance is.
We review the Core i5 3570K Ivy bridge processor. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i5 2500K and Core i7 2600K review
Today we test and review Sandy Bridge, the Intel Core i7-2600K and Intel Core i5-2500K processors. We will pair the 2600K processor with the Intel Desktop Motherboard DP67BG and also run a test with the Intel Core i5-2500K processor on a Intel DH67BL motherboard
Core i5 655K and Core i7 875K processor review
Intel today releases two new processors targeted at a somewhat more enthusiast audience. Yes, processors for tweakers and overclockers. On socket LGA 1156 Intel now releases two K series processors. The 32nm Intel Core i5-655K processor has the very same specifications as the Core i5 650; it will operate at 3.2 GHz, will feature two cores with Hyper-Threading technology, sport 4MB of L3 cache and will be made using 32nm process technology. The difference between the 650 and 655K is the unlocked multiplier only. Then we have the enthusiast class Intel Core i7-875K processor, it has the very same specifications as the Core i7 870; it will operate at 2.93GHz, will feature four cores with Hyper-Threading technology, sport 8MB of L3 cache and will be made using 45nm process technology. The only difference between the two central processing units (CPUs) will be the unlocked multiplier on the 875K chip, which will allow overclockers and enthusiasts to easily boost clock-speed of the product without the necessity of overclocking other parts of their systems.
Core i5 650 - 660 and 661 processor review
The time has come for Intel to debut a new line of mainstream 32nm processors, which we have all learned to recognize under the codename 'Clarkdale', the new CPUs will be aimed at the mainstream desktop PC segment and will complement the chip maker's Core i3 and Core i5 line of products. The Intel processor lineup will include the Core i3 530 and 540 models, as well as the Core i5 650, 660, 661, and 670, which will be featured with Hyper-Threading, 4MB of L3 cache and support for dual-channel DDR3-1333 memory. Well, that and an integrated GPU as well of course. Guru3D will put the Core i5 650, 660 and 661 to the test.
