What do i look for when buying a new cpu?

post #1 of 11
Thread Starter 
I guess ive always looked at the GHz but i guess thats not all i should look at it stats.

what else should i be looking for and what do the numbers mean?

what makes an i7 faster than a phenom II or vice versa

a lot of it comes down to things that can not be measured in numbers, it is the actual design of the chip.

what you have to do is look at benchmarks for the ones you are interested in and compare them by how they actually perform. the manufacturers will not give you that information, you must find it on the internet.

if you tell us your budget, we can help you find the best CPU, Motherboard, and RAM combination for your money.

When looking into CPU's, you should consider a few things:
Frequency (basically the gHz)
FSB Speed (speed at which your CPU communicates with mem)
Number of cores (higher the better)
Cache (more the better)
Power consumption (wattage)

It also depends on what you are using your CPU for? Are you encoding, gaming etc.?

You have the 955... So unless your not keen to OC, theres really only one way to go to stay AMD, and thats Thuban. FX isn't worth it, at all for the prices they want right now.

So... Thuban is your best upgrade path. If you want more than that, go 2500K.

But first, are you seeing CPU bottlenecks in things you do? If not or your just barely hitting some walls, perhaps a $25 or better cooler and a nice OC to 3.8 or so and see if that helps. And don't forget to check some AMD OC guides because AMD chips benefit well from a northbridge bump as well.

I have no idea which HDD's you have, or your ram for timing and freq, so I have no way to make a suggestion there. Low latency ram works well with AMD chips, perhaps even more important than freq. So theres a few things you can do that are very cheap if you don't NEED to upgrade (to save major $$ for perhaps a later, and more meaningful upgrade, or to make your upgrade cheaper)

So yea, we need more info to make a proper suggestion really. First things first, what are you doing on your computer and are you bottlenecked/limited by your CPU? And if so, by how much. And for the Thuban suggestion, its mainly only if you need more threads, if not or just gaming, and OC to the 955 would be the cheapest first attempt. Plus the cooler you buy can be used on your next CPU as well, so its no big worry if you end up having to upgrade the CPU as well, or sooner than expected.

If you are really looking too upgrade your 955 the only path would be Thuban. The higher binned AMD 9xx series will not give you much of a noticeable gain.

You could just OC your 955 harder... Look into after market coolers, they will help you greatly in ocing that chip. I fully support the Hyper 212+, there are other tower style coolers that will work just as well. You can also look at the Corsair Hx0 series, i would skip the H40 but the 60-100 should do wonders for that chip.

If you are just looking to make the whole system a bit more snappy, look into an SSD. Load an SSD with your OS, common games, and important programs and your system should feel like a new machine.

There are a lot of variables... Easiest way would be check out benchmarks like the others have stated.

Try overclocking yours and get an aftermarket cooler....H80 or H100 work very well!

or i5-2500k.

I went from a 1090T thuban to an i5 and it was night and day!

Ya, IPC(instructions per cycle) can't really be measured in numbers, stick to benchmarks to accurately gauge performance. Intel's IPC is usually always higher, and that makes up for the clock speed in some case. For example, a 2.66ghz i7 920 beats a 3.4ghz AMD CPU.
