Intel Core i7 920 Nehalem 2.66GHz Processor Review

Intel Core i7 920 Nehalem 2.66GHz Processor Review - PCSTATS
Abstract: If you're a computer enthusiast, you're likely already familiar with Intel's Core i7 processors, which have been widely hailed as the fastest desktop processors available on the market today. Introduced at the end of 2008, Intel's newest desktop processors are finally maturing and becoming more accessible in the market. It's time to take a look a fresh look at the Core i7 processor.

32-Bit CPU Rendering Benchmarks: Cinebench R10, Bibble 5

Cinebench R10 Source: CINEBENCH

CINEBENCH is a real-world test suite that assesses your computer's performace capabilities. CINEBENCH runs several tests on your computer to measure the performance of the main processor under real world circumstances. The benchmark application makes use of up to 16 CPUs or CPU cores to render a photo-reaslistic image. The scene makes use of various CPU-intensive features such as reflection, ambient occlusion, area lights and procedural shaders. In the first run, the benchmark only uses one CPU (or CPU core), to ascertain a reference value. On computers that have multiple CPUs or CPU cores and on those who simulate multiple CPUs (via HyperThreading or similar technolgies), MAXON CINEBENCH will run a second test using all available CPU power.

Higher results are best. Cinebench is multi-threaded.

Cinebench again shows the difference between single and multi-threaded performance. The first test has the faster clocked Core 2 Duo E8500 taking the lead, but this 3D ray tracing test can easily be scaled up to the Core i7's eight possible threads thanks to HyperThreading. With it full capabilites unleashed not even the Phenom II X4 955 Black Edition can keep up

Bibble 5.0 Source: Bibble Labs

Bibble 5 is a multi-threaded photographic workflow application that can be used to demonstrate the ability to scale work load across 4, 8, 16 or more processor cores. The basic process we will use for benchmarking is to convert a batch of 50 RAW image files from a digital SLR camera from their original RAW format to JPEG's at full resolution, using the applications default image settings.

Lower render times are best.

Intel Core 2 Duo E8500 29.2
Intel Core 2 Duo E8400 30.5
AMD Phenom II X4 955 Black Edition 17.9
AMD Phenom II X3 720 Black Edition (DDR3) 31.2
AMD Phenom II X2 550 Black Edition 38.3
AMD Athlon II X2 250 41.1

Bibble is a little glimpse into what the future will look like: a common application like photo-conversion that's been designed for multi-threading. It's a natural fit for the Core i7 920, and it gets an easy win here.
