Athlon II X3 435 processor review - Power Consumption and temperatures

Power Consumption

The new AM3 Athlon II X3 processor announced today has a fairly high TDP (peak wattage), this is 95W. Let's monitor what we get returned in full PC power consumption with the system in IDLE and with all the CPU cores stressed.

Power Consumption	idle	100% load
Athlon II X3 435	107	159

We notice our test platform peak out at roughly 160 Watts power consumption when we stress the CPU cores. Our system however idles merely at 107 Watts.

An important remark by the way; we added a dedicated graphics card (GTX 280), you'll notice that the end-result overall in idle and peak wattage is very impressive. If we'd have removed the dedicated GPU and went for the embedded graphics solution of the motherboard you could easily shave off another 50 Watts of power consumption, as that's roughly what a high-end graphics card consumes in an idle state.

Overall this is decent power consumption, remember this is a quad core processor. Mind you also that for benchmarking purposes we have energy saving features disabled. So when enabled, power consumption in IDLE would be even lower.

Temperatures

We did not have time to overclock just yet as the sample arrived shortly before release. But we did manage to stress it really well. Temperatures are almost sick, that low:

Idle temperature is 20 Degrees C / 68 F
Full 4 core LOAD is 28 Degrees C / 82 F

As you can see these are just really respectable numbers. We're curious is there's an offset (other reviews will tell). During our load-test we did place our finger on the copper heat sink base block, and it definitely was below body temperature.

We used an OCZ Vendetta 2 heatpipe cooler.

AMD Phenom II X6 1075T, X4 970BE and Athlon II X4 645 processor review
We test three AMD processors today, the Phenom II X6 1075T, Phenom II X4 970BE and Athlon II X4 645. They are part of the AMD Q4 processor product line update, arming their processor lineup with more value and higher performing CPUs.

Athlon II X3 435 processor review
Get this, a budget triple core processor that is clocked at nearly 3 GHz priced at roughly 55~60 EUR. The idea alone already oozes value, as whether or not we like to admit it, the current sweet spot in processors really is in-between two and four logical CPU cores. Today we'll be looking at such a triple core processor, the Athlon II X3 435 processor which is clocked at 2.9 GHz. Like other Athlon II processors, model 435 doesn't have Level 3 cache, and should not perform as well as the more expensive and powerful Phenom II X3 family. However in pure numeric tests the 435 beats Phenom II X3 720. Meet Rana ...

AMD Athlon II X4 620 review
AMD releases their Athlon II X4 620 and 630. That first one, the 620 will be priced at sub 100 USD prices, meaning you get to enjoy and reap the benefits of multi-core processing for 100 USD. These are the cheapest quad-core processors to date.

Athlon II X2 250 and Phenom II X2 550 BE review
AMD is announcing two new dual-core processors today, one based on the Phenom II architecture... the other branded under the Athlon II series. As such let me reveal the names, AMD launches their AM3 socket 45nm process based Athlon II X2 250 and Phenom II X2 550 BE. Have a peek at the two new AMD goblins.
