DryStone CPU test
We make use of a multi-threaded Dhrystone test, which basically is a suite of arithmetic and string manipulating programs. Since the whole program should be really small, it fits into the processor cache. It can be used to measure two aspects, both the processor's speed as well as the optimizing capabilities of the compiler. The resulting number is the number of executions of the program suite per second.
You can see all the way on top the QX9770 processor. Now look all the way to your right and compare it with the E6600 processor. This is a multi-threaded (uses all CPU cores) test, and it shows for sure.
Queen CPU test
This simple integer benchmark focuses on the branch prediction capabilities and the misprediction penalties of the CPU. It finds the solutions for the classic "Queens problem" on a 10 by 10 sized chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores. For example -- with HyperThreading disabled -- the Intel Northwood core processors get higher scores than the Intel Prescott core based ones due to the 20-step vs 31-step long pipeline. However, with enabled HyperThreading the picture is controversial, because due to architectural bottlenecks the Northwood core runs out of internal resources and slows down. Similarly, at the same clock speed AMD K8 class processors will be faster than AMD K7 ones due to the improved branch prediction capabilities of the K8 architecture.
CPU Queen test uses only the basic x86 instructions, it consumes less than 1 MB system memory and it is HyperThreading, multi-processor (SMP) and multi-core aware and thus is a multithreading CPU Benchmark with MMX, SSE2 and SSSE3 optimizations.
An excellent test to get some synthetic performance numbers. To the left the 250 USD Q6600 processor, to the right the 1400 USD QX9770 CPU.
ZLib CPU test
This integer benchmark measures combined CPU and memory subsystem performance through the public ZLib compression library Version 1.2.2
CPU ZLib test uses only the basic x86 instructions, and it is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware. Again a very good test to measure multi-core performance.
Core 2 Extreme QX9770 Quad-Core review
A couple of days ago we received a phone call from Intel with the question if we wanted to test an even faster Penryn CPU. Well, you know me .. when it comes to enthusiast products I'm like a bitch in heat, bring it on. In that previous article we already have you a good overview of the to be released Penryn products on Q1 of the next year. One of the products in that extensive line of 45nm products, actually the one on top, is the Core 2 Extreme QX9770 Quad core processor. The cream of the crop, top notch product.
Intel Core 2 Extreme QX9650 processor review
See, a Core 2 Extreme X6800 is pretty much the fastest desktop processor in the world, yet adding two more cores gives you the absolute best of both worlds. Get the highest stock clock speed Intel offers for the best performance in lightly multithreaded (or single threaded) applications, and a total of four cores for those heavy multitasking or CPU intensive multithreaded scenarios. Really, you can't lose there now can you ?
