GamePC heeft een review online gezet van de Intel Pentium III 750 (7.5 x 100) Coppermine processor. Uit de Quake III benchmarks blijkt nogmaals dat de Coppermine zwaar profiteert van haar full speed L2-cache; de 750MHz P3 blaast de Athlon 800 er dan ook met redelijk gemak uit.
As we see, the 750E is one mighty fast processor, the on-die L2 cache really does show an incredible performance boost. Considering the Athlon core is faster than the Coppermine core, we see the 750E Coppermine beating the 800 Athlon, squarely on the merits of the L2 cache. The Athlon's L2 is running at 320 MHz, whereas the Coppermine's L2 is running full-speed at 750 MHz. It's apparent that gaming uses a processor's cache quite frequently, and doesn't seem to be the more cache the better, rather, the faster the cache is the better. Quake III also takes advantage of Intel's SSE instruction sets, which also give a few FPS boost in performance.Overclocking is pretty tough with the 750E, considering it's high 7.5x multiplier, we got just what we expected when trying to overclock this chip, around 75 MHz. The chip boots and runs fine at 825 MHz, but at levels higher than that, it quickly freezes the system or blue-screens. It looks like Intel's yields aren't coming back too fantastic, but, it does run fine at the standard 750 MHz, and we can't really complain when a chip doesn't overclock too well. The 750E does run mighty warm compared to other Coppermine's, we had to switch two fans to get a powerful enough fan to cool it enough to run our stress tests, we finally ended up using Tennmax's SECC-2 unit, which kept the temperature just under 90ºF during 100% CPU utilization for long periods of time.
