AMD Athlon II 620 X4

Synthetic Tests part two

Synthetic Benchmarks cont...
 
 
Lavalys Everest Ultimate has a suite of great benchmarking tools and information available as we discovered here. The AES encryption test shows a linear increase between clock speed and score. PhotoWorxx displays a smaller increase, but this is also more dependant upon subsystems. CPU Queen however shows a 225 point increase over the theoretical improvement. Very impressive indeed. Although it's within tolerance nonetheless it's a good showing.
 
 
As we start to move away from purely CPU synthetic benchmarks to those that stress the whole system the difference lessens. PC Mark Vantage does seem more useful for testing everything, and it's here than the use of a standard HD and lower amount of memory really shows through. A 600 point increase for free isn't bad, but let's see if an actual program shows a similar lack of improvement.
 
 
PovRay is a script based freeware rendering program. As rendering is very processor intensive the improvement of 191 seconds (or 3 minutes 11 seconds) off of the stock speed time is very impressive. Again, like the CPU Queen test, faster than theoretically possible just based on the clock increase but within benchmark variances.
 
 
Cinema4D sees a reasonable improvement. One of the things that this graph doesn't show is that the normal clocked test showed a 3.64x processor scaling between single and multi-processor rendering, whereas the overclocked test showed 3.44x scale. Still a good result and proof that if you have any interest in graphics or rendering, this chip definitely should be on your shortlist.
 
Phew. Let's go and have a look at some game performance now we've covered every synthetic benchmark anyone could ever need.

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
