Futuremark 3DMark06 - CPU Test and PCMark05 CPU/Memory

3DMark06's test is a multi-threaded "gaming related" DirectX metric that's useful for comparing relative performance between similarly equipped systems. This test consists of different 3D scenes that are generated with a software and hardware GPU renderers, which is also dependant on the host CPU's performance. In its CPU tests, the calculations normally reserved for your 3D accelerator are instead sent to the host processor.
At the conclusion of this test, we did record a performance decrease of 2.5% with the "Brisbane" compared to the 90nm "Windsor". While not as severe as the latency we recorded in SANDRA, we are seeing a slight performance slowdown with the "Brisbane" core.

"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.
When the PCMark05 CPU test completed, once again, we saw a slight decrease in performance with "Brisbane" that equated to less than 1% compared to the "Windsor" based 5000+.

"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.
With memory specific performance, PCMark05's Memory module posted a 9% decrease in memory performance with the 65nm "Brisbane" vs the 90nm "Windsor" core. This is a fairly major drop in our opinion, however, we'd like to see how this translates in real world application testing before drawing any conclusion.
