Which CPU is Better?

[pebbleberries]

I have 2 Options for a CPU for a cheap, tiny rig.

Which one is better?

Xeon X5482 or Core 2 Quad Q9640

The xeon takes more power and has a higher clock.

The system will have 8gb ddr3 and a gtx 750 ti.

Core 2 quad is $70

Xeon is $30


Xeon is more powerful but consumes more power and costs more.

C2Q is Cheaper, more efficient but is a tiny bit slower.

What do you recommend?

Xeon CPUs don't usually work with normal motherboards, and ram, plus the Xeon isn't the best for gaming, I would say the core 2 quad would be a better choice

 

[pebbleberries]

That's what I was leaning towards anyway.

My friend used an LGA 771 CPU with an LGA 775 motherboard with the little orange sticker.

None of them can support DDR3

 

[pebbleberries]

Do no Core 2 quads support DDR3?

 

[EdgeT]

Nope, not as far as I know

 

[pebbleberries]

The spec sheet for the motherboard says any 775 C2Q, C2D, Celeron or pentium.

It is a ddr3 board. I have ddr3 in it right now.


I know another motherboard that supports that CPU and has 4 memory slots. 2 ddr2 and 2 ddr3.

C2Qs still use a FSB, and the memory controller is on the board, not the CPU like modern chips. I don't follow Xeons so I can't say which is better.

I know another motherboard that supports that CPU and has 4 memory slots. 2 ddr2 and 2 ddr3.

Every board I've ever seen with this setup only allows one type of ram to run at a time. If you try to use all four slots together it won't work. You have two DDR2 slots OR two DDR3 slots.

 

[pebbleberries]

I know you can only use 1 type of ram at a time. I just thought it was interesting.

Intel Core 2 chipsets did indeed support DDR3 since P35. The important thing to remember is they can only take very low-density DDR3 with 2Gbit chips that haven't been made in 7 years--Intel CPUs with IMC can take up to 4Gbit chips (8GB sticks) while AMD can take 8Gbit chips (16GB sticks). That's why some DDR3 is advertised as "AMD only."

These CPUs have no onboard memory controller so could not know about or "support" any type of memory. They can only communicate over FSB.

Assuming you have the appropriate board, X5470 is the best Xeon for this purpose as it has a 10x multiplier allowing for 4GHz operation at the same 1600FSB as the X5482. X5460 is nearly as good at 9.5x for 3.8GHz at the same FSB. Both are better than the Q9650 which is only 9x so would require 444MHz = 1776FSB in order to reach 4.0GHz, and unlike duals, many quads do not easily reach high FSBs. The X5482 is even worse with its 8x multiplier, unless you are content with nearly stock speeds.

 

[pebbleberries]

Ohhh ok. Well I am going with the q9650 because it is way cheaper. Also who knows if the xeon will work in the board.

It has 8gb ddr3 in it right now. I just need the 750 ti and the q9650.

 

[BFG-9000]

If you have a board that can accept Xeon microcodes on this list, then a Xeon X5460 that's premodded to drop into S775 (no modifying the socket needed) and welded pads (no dumb sticker) is only $24 on eBay.

That's much less than a Q9650.

You already have the maximum possible amount of DDR3 for Core 2. Many DDR2 boards could accept 16GB.

 

[pebbleberries]

I wasn't really thinking less than the x5482. The X5460 is a bit cheaper.

My current gaming desktop has an X5450 with 6gb ram and a gtx 690. It will Be getting an overhaul with a i7 6700k which I found for about 170$ CAD, 16gb 3200 MHz RAM. and a beautiful Asus motherboard.

I probably won't need more than 8gb for the tiny rig. (Actually a high end Lenovo thinkcentre m58 6258 which I have 30 of from an ewaste bin.

Me, here in 2024 resurrecting an old lga775 pc that currently has an e8400 on an annus p5qld pro motherboard. I Bought a cheap 256gb ssd on aliexpress, flashed the bios with latest bios with microcodes and I'm choosing which xeon to buy for cheap on aliexpress too. I was just lurking arround if I should go with the 1600fsb ones or 1333. you actually answered it for me... will go that route and just settle with an X5460 and use a modern air cooler on it and let's see what I can crank out of him... Will have an spare 360mm watercooler soon but would need to mode the case to fit... Using only cheap stuff to upgrade it...
