The Intel P8700 is a Core 2 Duo, 3MB L2 cache, 1,067MHz-FSB, whereas. The T9400is a Core 2 Duo, 3MB L2 cache, 1,067MHz-FSB. The only difference is the L2 cache. 3MB vs. 6MB, as far as I know. However, what's with the Pxxx vs. Txxx?? Is there any other difference based on that?
View 9 RepliesI like the CPU speed control in Power-->Advaanced settings, with precision to 1%. We've always had it in IBm Thinkpads, since IBm sold it to China which rebranded it as Lenovo, I switched to American HP. Regular Windows, not taylored by IBM, was never aware of Thinkpads unique internals. Now with Vista it doesn't matter, i can control processor and I CAN SEE & HEAR RESULTS! Suppose fan is blowing and my hand can feel warm air flowing from vents, I tested it several times when I switch from CPU 100% to 25%, fan slows down stops, air gets cooler, and fan is often stopped which gives me some peace in temrs of reliability. A hot computer is bound to sustain permanent damage, heat is the biggest killer of electronics. So I switch to 100% when running CAD & Graphics/Video apps, 25% when writing articles, 10% when reading/browsign plain text, of course I don't annoy myself by clicking switches and playign with this instead of real work.
But still i appreciate this control, because I my profession is electroncis-related I just like this type of clock frequency control. IBM also provided us with automatic CPU, automatic PCI bus or fixed PCI bus frequency, optical drive turn-off time in addiiton to harddisk timer found for real techies who get deep into hardware, we don't have that in Vista but I don't care. I have a real quiet laptop now despite its gigantic 17inch display and hardware meant for hard-core CAD, Graphics & Gaming, you don't alway sneed processor toiling hard in summer heat, only asking for potential fan damage-->CPU damage, so thsi control is nice....
I just bought a new pc with Vista Home Premium, it came with: 1GB PC2-6400 DDR2 SDRAM, expandable to 4GB. I wanted more memory so I bought a 2GB kit PC2-*5300* DDR2 SDRAM, because it was on sale for $60. The 6400 speed would have cost me over $200. The salesman assured me it would work fine and I wouldn't notice any difference. I installed it when I got home and everything works great, no problems. But I still can't stop wondering if the difference in speed WOULD matter. Can anyone explain, or provide a link explaining, when, if ever, I would benefit from the faster memory. I mostly use my PC for surfing the web, email, and some photo editing.
