Date  15th March 2005 Author  Chainbolt Editor  James "Agg" Rolfe Manufacturer  Intel CPU & Bandwidth Benchmarks, General Usage CPU AND BANDWIDTH BENCHMARKS: At first we have a short look at some popular synthetic benchmarks for CPU and memory bandwidth. Both CPU benchmarks show the 650 leading the 550 by a healthy margin thanks to the additional cache. We also see that the 3.73 GHz EE is far ahead of the 3.46 GHz EE. The same holds true for bandwidth: The 650 has gained on the 550, although both processors are running at a FSB of 800 MHz. The 3.73 GHz EE running at 1066 MHz shows an impressive bandwidth of more than 6600 MB/sec and claims the bandwidth crown back for Intel. This result shows that the A64 low latency on-die memory controller doesn’t guarantee better bandwidth than Intel’s off-die controller with higher (worse) latency. According to these results a 3.73 GHz EE based system should perform clearly better than an A64 based FX55 based system. As we will later see this is not always the case, in particular not in gaming, and that shows that such synthetic benchmarks have limited value to gauge real world performance. GENERAL USAGE APPLICATIONS: All test results in this section and most of the following are based on PCWorld’s WorldBench 5.0. This benchmark is based on widely used desktop applications and has become an industry standard for PC benchmarking. WorldBench includes 2 applications for data compression and archiving: WinRAR and WinZip. WinZip shows almost no difference between a 550 and 650; obviously the larger L2 cache on the 650 has no visible impact. WinRAR performance as measured in KB/sec depends almost exclusively on processor performance and is therefore more sensitive for changes to the architecture such as a bigger cache. Here we can see the 650 is leading the 550 by around 4%. In Microsoft Office XP and Ahead Nero we see only minor differences between all processors in our tests. 650 and 550 performance is almost identical. The larger cache seems to have little impact when these applications are running. With the exception of WinRAR we found the P4 CPUs performing slightly better in these applications than the A64s. << Back Next Page: >> Select Page Page 1 - Page 2 - Page 3 - Page 4 - Page 5 - Page 6 -
