AMD Phenom II X4 830 vs 840

post #1 of 27
Thread Starter 
MC has the 830 OEM for $50 and 840 retail for $60. I'm going today.


I will be getting an aftermarket heatsink. Any benefit other than stock clockspeed of getting the 840?

The 830 has L3 Cache and the 840 doesn't. I believe the 830 uses Phenom cores as well, but the 840 doesn't.

So....
830 = Deneb
840 = Propus (Deneb without L3)



The 830 is just better then?

Yes, the 830 is a much better option. I'm actually going to pick mine up from MC today as well. Very good CPU for a budget build.

Never been on an 830 so can't compare but I love my 840 got it overclocked to 4.1ghz with h100. Does everything I ask it do do.

The L3 cache is the difference. AMD lies and calls the 840 a Phenom when it's really an Athlon.....

The x4 830 is a relabelled x4 925
post #9 of 27
L3 Cache makes 5% to 15% difference in any application. That means 830 would be better choice.

I just bought a Phenom II x4 830 to replace a 840 last week. I OC'd the 840 to 3.9 GHz @ 1.488 Volts, while I OC'd the 830 to 3.5 GHz @ 1.367 Volts. Despite the 400 MHz disadvantage the 830 beats the 840 in every gaming benchmark I could throw at it.
In the 3DMARK 11 test alone I saw an astonishing 1000 point improvement!!!
I then submited a Stalker Call of Pripyat benchmark score that received a better then 91% of all other submitions ranking, up from a 82%... that's a 9% increase in ranking, and the only difference, is the processor, and the voltage setting.
My Windows 7 WEI processor score dropped from 7.5 to 7.4, however my memory score somehow went up from 7.5 to 7.7, perhaps having a L3 cache takes some of the burdon off my system memory.
My Super Pi scores are now slightly lower as well, for what ever that's worth...
In real life gaming I've noticed a huge difference, Borderlands 10 FPS improvement, and in BFBC2 I now rarely drop below the 100 FPS mark, and thats on ultra settings!
The cherry on the sundae is, my temps max out about 12 deg. lower on the 830, I have yet to see it get hotter then 39 deg., my 840 would hit 52 deg. while stress testing.
Phenom II x4 830 vs Phenom II x4 840... Come on... it's a no brainer the 830 by a knock-out! thumb.gif
