Solved Help me to choose a Core2quad processor

Toshiba Satellite c655-s5082 laptop

Specs: Windows 7Ultimate (64 bits), Intel Core i3-2350M (2.3GHz) / Kingston 2x2gb DDR3
Hi, I have to choose between these 2 processors, I only have to keep one:

Intel Core2 Quad Q8400

or:

Intel Core2 Quad Q6600

In this page it says Q8400 is better, but also says that Q6600 has more caché and this is better: http://cpuboss.com/cpus/Intel-Core2...

Which one you should choose and why?

Thanks in advance!

Mobo: Intel(R) DG41RQ
CPU: Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz
RAM: Kingston 2MB PC2-6400 (400 MHz)
Video: nVidia GEFORCE 8400GS 512MB
Audio: Realtek High Definition Audio

I'm guessing your Intel motherboard doesn't let you overclock, so I'd go with the Q8400. The higher core and FSB speeds along with the increased IPC of the Wolfdale core should more than make up for the smaller cache.

mATX LGA2011 | i7-4930k @ 4.3GHz | 32GB DDR3-2133 | GTX 970 | Rampage IV Gene
512GB/4TB/BDXL | Win 10 Pro

Yes, it seems my mobo does'nt let me any overclocking.... this PC is used mostly for gaming, old games and emulation of PS2 and other similar, I thought the more cache would give a little bit more good experience in gaming.

It seems no...

✔ Best Answer
L2 cache is the least of your problems.

Your system is somewhat outdated but the biggest deterrent to better performance is the Intel motherboard. If you had an overclockabled aftermarket board (Asus, Gigabyte, MSI, etc), you'd be able to make your system scream without even swapping the CPU.

For example, changing the E7500 clock settings from it's defaults of 11 x 266MHz (2.93GHz) to say, 8 x 400MHz (3.2GHz), would not only increase the FSB speed by 50%, but it would allow you to take full advantage of your DDR2-800 memory. You'd be running the CPU:DRAM freq ratio at the desired 1:1. Right now, your RAM & CPU are out of sync, running at the less than optimal ratio of 2:3.

If you're not going to change the motherboard, the Q8400 is the CPU to go with. And get a decent video card too. Your last post you asked about the onboard X4500 vs the 8400GS...they both suck for gaming.

Yeah I know my hardware is suck for games, but the games I try to play are quite old, Silent Hill Homecoming, Metal Gear Solid 2, but mostly emulators like Playstation 2 and Wii/GameCube, all of them runs very well in this ancient hardware.

Anyway, I think newer games are for retards, since in every step you do a hint is popup, and this is so annoying, I prefer my old games.

Thanks, I'll keep my DG41RQ+Q8400+8400GS for my purposes.

It's not about playing newer games, it's about getting the best performance out of your system. No matter which CPU you install, the Intel board is going to hold you back. And if all you play is old games anyway, why upgrade the CPU at all? None of those games will take advantage of the quad-core CPU. What little you gain from the faster FSB will be negated by the lower overall clock speed, plus your CPU & DRAM frequencies will still be out of sync at 333:400 (5:6).

Assuming you're buying the CPU & you're not getting it for free, you'd be much better off putting that money toward a decent motherboard instead. Keep the CPU you have, get an aftermarket board based on a better Intel chipset (P43 or P45; G43 or G45 if you want IGP), overclock it to get the CPU:RAM in sync, & then sell the old motherboard for whatever you can get.

And if you haven't gone back to your other post, get GPUZ to identify which 8400GS you have:
