Upgrading CPU (939)

[sep]

Do you think I'll see a big difference going from the 4200+ to the 4800+ ?

?

200mhz difference ? No, not going to see a big difference if any at all. Overlock your 4200+, you should be able to do it by 10% default in the mobo's bios. You can do it manually to ofcourse, and with some luck you can overclock it to 2.4-2.6ghz or higher.

 

[LiquidImpulse]

nope, you will notice little if none difference in performance imo.

Even with the cache increased (512 to 1mb)?

I went from a 3800 to a 4800. The benchmarks scored a little higher but the change in the "feel" of the system was barely noticable.

 

[Bateluer]

Depending on what apps you use, you might notice something, but odds are its not a very worthwhile upgrade. Unless you get a really kickass deal on the 4800, I wouldn't bother.

save yourself the money, you can probably overclock your current chip 200mhz. there has to be at least a little wiggle room even if it was a bad chip. if you dont want to overclock and like to waste your money, go ahead, but socket 939 is dead so if your going to do it, better do it now before all the 939 chips are gone.

 

[biostud]

probably not

Overclock the processor, save the $ for a faster graphics card instead.

 

[nyker96]

why not upgrade to a c2d, if you do video encodning, graphics stuff, you'll see a big diff say between a 3ghz OCed X2 vs. 3ghz C2D

 

[themisfit610]

Definitely.

I think the only reason to upgrade a 939 box would be to go from single core to dual core. That's a big step up in most cases.

Going from a slow dual core to a faster one on a 939 is a waste of money. That $100-150 you're spending should be going to a new board, chip, and RAM

That would be a stunning waste of money. Avoid doing so at all costs unless you're getting a tremendous deal on the 4800+.

Well my only reason to upgrade would be to compliment a GTS/GTX or GT in my rig for GAMING. I'm going to upgrade the video card first. If the processor needs adjusting I'll try overclocking a little, but I'll have to agree with you...money should go towards new MB/CPU/RAM. Thanks -JC

If you are changing generations you'll see more than that 200mhz gives esp. if more cache and better instruction sets.

I went from a Winchester 3200+ to a San Diego 4000+. I was at 2520 on my winnie, now at 2830 on the San Diego. (280x9 vs 283x10).

I noticed a pretty big difference in games and the like...more than I thought I would.

Encoding and decoding is majorly better and of course synthetic benchmarking.

I'd really like to go to an Opt. 185 next.

After that I think a DX10 class video card could hold my machine competitive for a couple more years.

Even with the cache increased (512 to 1mb)?

Increasing the cache on a socket 939 X2 gives you maybe 2-3 % better performance.

"As to 512 Cache vs 1mb cache, it depends on the program. With some programs the larger cache makes no difference with others it the 1mb cache gives about 5% to 10% more performance. A lot of games get 5 to 10 more FPS with the larger cache."

"Here are a couple of applications that actually take a slight advantage of the additional cache on the FX line."

All of the performance differences you are seeing in the benchmarks we showed you are a result of the lack of 512 KB of L2 cache. The performance benefits of this additional cache on the FX line are very small, making me question what sense it makes to have two separate lines of processors for the desktop market.

So, that 2 x 1MB cache is not a big deal.

looks like 5-10% was given not 2-3%. 5-10fps is pretty major though in a game.

No. That won't make any difference.

This sort of increase from L2 cache is usually only seen in CPU-limited situtations (where fps are likely to be >>60).

If you are looking at the s939 OEM model 4800+ at Newegg, the cost is $120.

For about $150 you can get this motherboard that will let you reuse your DDR1 RAM and AGP video card (has pci-e slot too for future upgrade or if that's what you have now) and a 2GHz e2180.

Or you could add an extra $50 and get the e4400 which would be even better for gaming.
