AMD Athlon II 620 X4

Synthetic Tests part one

Synthetic Benchmarks
 
Whilst not always an indicator of actual performance, synthetic benchmarks have a place in our hearts because there is nothing like the purity of numbers to give a feel for the capability of a processor or system, and you can also get a feel for how much extra performance to expect in general usage from an overclock.
 
 
SiSoft Sandra shows that the overclock of 25% gives an improvement of around 23% in the Arithmetic tests. Not bad at all as we know that you never get a one to one improvement.
 
 
The Multi-Media test showed an even higher improvement. Maths tells us that if we saw a one to one improvement via the clock speed then our Multi-Media Int overclocked result would be 149591. We actually got 149134 showing that this is one theoretical test that gets very close to a direct increase when the processor is overclocked.
 
 
7-Zip 64 bit comes with a built in benchmark. For this test we used the 32MB dictionary and ran 6 passes. This more real-world test showed similar results to the above two, in that this scales very well with little loss in performance between theoretical increase and that seen by the end user.
 
 
It wouldn't be CPU review without the old favourite SuperPI. In this case, whilst there is a clear improvement between the stock and overclocked tests, the 1M result isn't exactly earth shattering. Not bad for a disappointing overclock on a L3 disabled processor, but I was expecting around 20 seconds.
 
Let's go and see some more synthetic results.

Welcome to the team VB!

The X4 620 certainly is a stonking processor for the money, though my hunch is that the OC limitation lies with the motherboard. 250HTT can often be a real struggle for some boards. It may have been a CPU related limitation if the mobo didn't offer a decremental NB multiplier.

Good work! Quote

Thanks Mul.

It was the most frustrating OC I've ever attempted. Usually you get towards it and gradually strike the balance between stability and the CPUz screengrab of death. This was just all or nothing.

It's amazing value for money though.Quote

Picked one of these up last week actually... Gotta say for the cash it is a complete bargain. I managed 3.4Ghz but unstable. Running at 3.2GHz very stable

At £70-80 for a 3.2GHz Quad CPU you can't complain at all

Nice review VB Quote

Great review VB.

I think I'm alone in feeling uneasy about the pricing on this.

I do accept that, yes it's quad core, and yes it'll capably handle what's thrown at it - and I can see oc'ers liking this.

So why the uneasy feeling... perhaps if the £77 is mrrp and it onlines at £70 or a snatch under, I'd feel a little better.

But I think I latch onto the superpi score (which there is a multicore version available now I think I've seen), just under 25s for an oc. Then look over at Intel's camp, especially considering the £220 mobo/cpu idea. Intel are ofc making the adjustments too, and they're 'pentiumizing' previous c2d cpus, and yeah they're 2 cores (if u bank on 4 cores, or have a legit reason to think ur software will use it - ur not really on a budget imo) - but they are more attractively priced imo, and ofc they oc too.

Tough one.Quote

Very good review, and looks like the chip is going to be a bit of a bargain, to check if the 250fsb is the limit did you drop the multiplier down?, this may give an indicator if the 250fsb is the problem or the 3.2ghz clock is the limit Quote
