Ook Sharky Extreme heeft nu een review in elkaar getypt van de nieuwe Pentium 3 533B en 600B processors met 133MHz FSB ondersteuning. Hier heb je het gedeelte over de performance, de rest van het verhaal staat hier.
Beginning with our 3D-application suite of tests, which is comprised entirely of game based benchmarks, we see that the increase of both the CPU's and the memory's bus speed does enable a small performance boost.
Even though the amount of total ram, the two CPU's core speeds, and the video cards were kept the same between the two systems, the P3-600B exceeded the standard P3-600 in speed by up to 5% in optimal conditions.
This is enough of a boost to similarly allow the new P3-533B CPU to compete stride for stride with the P3-550MHz CPU in the same tests, although at this point the two models are nearly identical in price so there's no outright advantage in choosing the new 533B over the older 550.
In our synthetic 2D test suite, we noticed that under most of the tests that are based on real-world apps like PhotoShop and Naturally Speaking, the faster bus speed allowed the P3-533B to actually outperform the vastly more expensive P3-600/100 CPU.
We also noted similar gains when using Intel's platform bandwidth tests, which move large amounts of data across both the video and memory busses system-wide.
The end conclusion that readers can take from these results is that a faster front side bus speed can assist in generating faster performance under certain conditions, specifically in apps that utilize a tremendous amount of memory.
Games however can only benefit slightly from this bandwidth boost (games of late '99 and early 2000 anyway) and that's only at the lower video resolutions where video cards are not as fill-rate limited.
[break]Hm, en als je trouwens denkt dat je deze 133MHz FSB CPU's goed kan overklokken heb je het mis...[/break]
Even with these impressive preparations, we still weren't able to hit either the 600MHz mark for the P3-533B or the 675MHz mark for the P3-600B from the charts above, which was disappointing. Much of overclocking success or failure still lies with the CPU itself, if it's not capable of running at a higher speed with stability then it likely won't no matter what the user opts to try.
Even when cooled to 2 degrees C, we couldn't achieve the speeds that we felt would make the level of effort worth while.
Hopefully as higher volumes of both mainboards and memory that are capable of frequencies of 133MHz and higher are achieved we'll all be able to pursue more overclocking possibilities. For now though, we're still very limited by system level components as well as the CPU's cores themselves.
