AMD Athlon II X4 620 Processor Review

 AMD Athlon II X4 620 Processor Review

Priced between the Athlon II X2 250 and the Core i3-530 – is this processor better than either of them? Is it work considering?

The Processor

Here’s the Athlon II X4 620 itself.

Here’s the stock heatsink. The heatsink itself is a taller than the one for the X2 250.

Here’s the CPU-Z capture of the processor on overclock, I did a quick 20% overclock and it seemed to work fine, I know it shows lower voltage on the screenshot but on the BIOS side I just added 0.01 to it.

Test Setup

The test setup used for this review.

Processor AMD Athlon II X4 620
RAM OCZ 1066mhz 4GB Dual-Channel Kit
Motherboard MSI 770-C45
Graphic card Galaxy GT220 1GB DDR3
Cooler Stock heatsink
Monitor 20″ Dell Ultra-sharp Wide-screen LCD

Benchmarks

The Athlon II X4 620 is benched in both stock and overclocked state, it will be compared to the Athlon II X2 250 and the Intel Core i3-530

Super PI 1.5 Mod

The value chosen for Super PI was 1M.

X4 620 X4 620 OC X2 250 i3-530
29.999 25.537 27.003 14.508
* Lower the better

Super PI is a single-core benchmark. The 2.6ghz alone is running behind the X2 250’s 3ghz single core speed. Both of them of course, being behind the i3-530.

CINEBENCH R10

Processor X4 620 X4 620 OC X2 250 i3-530
Rendering (Single CPU) 2237 2667 2311 3323
Rendering (Multiple CPU) 8088 9583 5193 7511

The benchmark was done with default settings. Here’s where you can download MAXON CINEBENCH R10.

The X4 620 shines here as it is the only TRUE quad-core in among the pack.

PCMark Vantage

X4 620 X4 620 OC X2 250 i3-530

* Higher the better

Fritz Chess Benchmark

Processor X4 620 X4 620 OC X2 250 i3-530
Relative Speed 12.52 15.24 7.67 17.25
Kilo Nodes/second 6011 7402 3680 8280

While a lot faster than the X2, it is still behind the i3-530 but the gap is much reduced after having 20% overclock.

The i3-530 is a speed demon but being just a dual-core with Hyper-Threading (2 cores, 2 threads per core), the performance is less impressive compared to true quad cores (4 cores, 1 thread per core)

Thermal Performance

Tests were done with the stock heatsink.

Processor X4 620 X4 620 OC
Idle 28°C 28°C
Load 49°C 53°C

Temperature looks good for a quad core. I had quite a few quad cores with me and they all seem very hot. The X4 620 runs pretty cool in my book, despite having being a 95w TDP processor.

Conclusion

The AMD Athlon X4 620 is an awesome processor in my book. Compared to the X2 250, it costs about RM 100 (about 40%) extra but you get 4 cores running at 2.6ghz with 512Kb L2 cache per core instead of 2 cores at 3.0ghz with 1Mb L2 cache per core.

Compared to the i3-530, it is 75% the cost but you get 4 cores instead of 2 cores with 4 threads.

Despite the comparison above, it is in no way saying any of those processors are bad – they all have their strengths and weaknesses. The X4 620 shines most when the application utilizes quad-core processing power.
