AMD Athlon 64 X2 6000+
PCMark05: CPU and Memory
For our next round of synthetic benchmarks, we ran the CPU and memory performance modules built into Futuremark's PCMark05 suite.
"The CPU test suite is a collection of tests that are run to isolate the performance of the CPU. The CPU Test Suite also includes multithreading: two of the test scenarios are run multithreaded; the other including two simultaneous tests and the other running four tests simultaneously. The remaining six tests are run single threaded. Operations include, File Compression/Decompression, Encryption/Decryption, Image Decompression, and Audio Compression" - Courtesy FutureMark Corp.
PCMark05's multi-threaded CPU benchmark had the new Athlon 64 X2 6000+ finishing just ahead of the Athlon 64 FX-62, but the Quad-FX platform and Intel's dual- and quad-core Core 2 processors both outpaced the AM2-based processors.
"The Memory test suite is a collection of tests that isolate the performance of the memory subsystem. The memory subsystem consists of various devices on the PC. This includes the main memory, the CPU internal cache (known as the L1 cache) and the external cache (known as the L2 cache). As it is difficult to find applications that only stress the memory, we explicitly developed a set of tests geared for this purpose. The tests are written in C++ and assembly. They include: Reading data blocks from memory, Writing data blocks to memory performing copy operations on data blocks, random access to data items and latency testing." - Courtesy FutureMark Corp.
The performance deltas separating AMD's socket AM2 dual-core processors (the FX-62 and 6000+) and Intel's Core 2 processors in PCMark05's memory performance module were relatively small in comparison to the previous results. The Intel CPU's still came out on top though. The Quad-FX platform, however, put up comparatively lower scores here due to its non-unified memory architecture. To improve the Quad-FX platform's memory performance, it should be running under 64-bit environment with proper support for NUMA, namely XP-64 or Vista.
