AIDA64 Extreme Edition Tests
AIDA64 Extreme Edition is the evolution of Lavalys' "Everest Ultimate Edition". Hungarian developer FinalWire acquired the rights to Everest in late November 2010, and renamed the product "AIDA64". The Everest product was discontinued and FinalWire is offering 1-year license keys to those with active Everest keys.
AIDA64 is a full 64-bit benchmark and test suite utilizing MMX, 3DNow! and SSE instruction set extensions, and will scale up to 32 processor cores. An enhanced 64-bit System Stability Test module is also available to stress the whole system to its limits. For legacy processors all benchmarks and the System Stability Test are available in 32-bit versions as well. Additionally, AIDA64 adds new hardware to its database, including 300 solid-state drives. On top of the usual ATA auto-detect information the new SSD database enables AIDA64 to display flash memory type, controller model, physical dimensions, and data transfer performance data. AIDA64 v1.00 also implements SSD-specific SMART disk health information for Indilinx, Intel, JMicron, Samsung, and SandForce controllers.
All of the benchmarks used in this test— Queen, Photoworxx, ZLib, hash, and AES— rely on basic x86 instructions, and consume very littlr system memory while also being aware of Hyper-Threading, multi-processors, and multi-core processors. Of all the tests in this review, AIDA64 is the one that best isolates the processor's performance from the rest of the system. While this is useful in that it more directly compares processor performance, readers should remember that virtually no "real world" programs will mirror these results.
Queen and Photoworxx tests are synthetic benchmarks that iterate the function many times and over-exaggerate what the real-world performance would be like. The Queen benchmark focuses on the branch prediction capabilities and misprediction penalties of the CPU. It does this by finding possible solutions to the classic queen problem on a chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores.
Here we see the $159 AMD 965 Black Edition handily beating the $185 Intel Core i5-750, while the $199 AMD 1075T and $229 AMD 1090T run just behind Intel's $280 Core i7-930. The overclocked 11100T beats everything except the i7-980X, which runs away from the pack with results 39% better than the next closest competitor.
Like the Queen benchmark, the Photoworxx tests for penalties against pipeline architecture. The synthetic Photoworxx benchmark stresses the integer arithmetic and multiplication execution units of the CPU and also the memory subsystem. Due to the fact that this test performs high memory read/write traffic, it cannot effectively scale in situations where more than two processing threads are used. The AIDIA64 fPhotoworxx benchmark performs the following tasks on a very large RGB image:
The Intel processors dominate these results, with every Intel CPU doing substantially better than every AMD CPU. Since this test cannot effectively use more than two threads, the hexacore processors have no advantage over quad-core processors. AMD 965 Black Edition is the best performer in the AMD camp, outperforming even the overclocked 1100T. The worst performance is turned in by the stock-clocked Phenom-II X6-1100T, and the best, as usual, by the 980X.
The Zip Library test measures combined CPU and memory subsystem performance through the public ZLib compression library. ZLib is designed as a free lossless data compression library for use on virtually any computer hardware and operating system. The ZLib data format is itself portable across platforms and has a data-independent footprint that can be reduced at some cost in compression. The AES integer benchmark measures CPU performance using AES data encryption. It utilizes Vincent Rijmen, Antoon Bosselaers and Paulo Barreto's public domain C code in ECB mode and consumes 48 MB of memory. Both of these tests are much more applicable to the "real world" than the previous tests.
The results of the Zip compression test scale almost linearly with processor clock speed on the quad-core Intel side, but there's some threading going on as can be seen with the Core i7-980X results, where two extra cores and an extra 530MHz or so virtually double the performance of the i7-930. Extra cores help on the AMD side, too, with all of the hexa-core CPUs handily outperforming the 3.4GHz quad-core 965 Black Edition.
The AES encryption test is utterly dominated by the Core i7-980X, whose performance is 6.7x better than its closest competitor. The reason is Intel's Advanced Encryption Standard New Instructions (AES-NI), which dramatically accelerate AES code. AES-NI aside, the AMD processors uniformly perform better than the Intel processors without this feature. Other than this, we see a nice, even progression as processor clock speed and number of cores increases. Note that the very high score for the Intel 980X visually diminishes the performance differences among the other processors.
AIDA64's Hash test is new (it wasn't in Everest). The 64-bit hash benchmark measures CPU performance using the SHA1 hashing algorithm. Written in assembler code, the Hash benchmark is optimized for every popular AMD, Intel and VIA processor core variants by utilizing the appropriate MMX, MMX+/SSE, SSE2, or SSSE3 instruction set extension.
The Intel results are a little uneven, with the 2.66GHz, non-Hyper Threaded Core i5-750 beating, by just a little, the 2.8GHz Hyper-Threaded Core i7-930. On the AMD side, we see a very smooth progression and clock speed and number of cores increase. In fact, the scores of the four hexa-core processors scale in perfect lock-step with their frequencies.
