AMD Athlon II X3 435 2.9 GHz Socket AM3 Triple-Core Processor Review

AMD Athlon II X3 435 2.9 GHz Socket AM3 Triple-Core Processor Review - PCSTATS
Abstract: Enter the AMD Athlon II X3 435 processor, the focus of this PCSTATS review. It's a 2.9GHz triple-core socket AM3 CPU built on the Propus die. So is it better to get a dual core CPU, a triple-core CPU or a quad-core CPU?

Processor Power Draw, Core-by-Core

While the AMD "Deneb" die is rated at 140W TDP, the "Propus" die requires significantly less power, just 95W TDP.

To determine how much power multi-core processors draw, PCSTATS will be measuring total power consumption what the CPU is in idle and several CPU-stressed states. To get an accurate measurement, it's necessary to disable AMD and Intel's power saving and CPU clock speed throttling technologies like Cool 'n' Quiet, EIST (speedstep) and C1E power states. To simulate single-core load a program called Stress Prime (SP2004) is used.

PCSTATS set about stressing each processor from one to all cores. This programs gives better insight into different power draw scenarios. The SP2004 program is multi-threaded, allowing individual CPU cores to be stressed by each instance of the program.

Total system power consumption was read with the Extech Power Analyzer Datalogger (model 380803). The Extech Power Analyzer is located between the main 120AC supply and the PC's power supply.

Total System Idle Power Draw
Processor Total System Power Draw
Intel Pentium 4 540 150 Watts
Intel Pentium D 840 165 Watts
Intel Pentium D 940 168 Watts
Intel Core 2 Duo E6600 117 Watts
Intel Core 2 Duo E6750 123 Watts
Intel Core 2 Duo E8400 131 Watts
Intel Core i7 920 144 Watts
AMD Sempron 3600+ 120 Watts
AMD Athlon64 4000+ 163 Watts
AMD Athlon64 FX-60 127 Watts
AMD Athlon64 X2 4800+ 143 Watts
AMD Athlon64 X2 5000+ 156 Watts
AMD Athlon64 FX-62 168 Watts
AMD Athlon II X2 240e 122 Watts
AMD Athlon II X2 250 128 Watts
AMD Athlon II X3 435 130 Watts
AMD Athlon II X4 620 130 Watts
AMD Phenom II X3 720 155 Watts
AMD Phenom II X4 955 148 Watts
AMD Phenom II X4 965 154 Watts

The AMD Athlon II X3 435 test system draws about as much power as the AMD Athlon II X4 620 based PC, as expected. AMD has a come long way in terms of idle power consumption, and its newer 45nm mainstream processors are quite competitive with Intel here.

Total System Stressed Power Draw - All Cores/Threads
Processor Total System Power Draw (All Cores)
Intel Pentium 4 540 223 Watts
Intel Pentium D 840 (2 Core ) 240 Watts
Intel Pentium D 940 (2 Core Load) 253 Watts
Intel Core 2 Duo E6600 (2 Core Load) 156 Watts
Intel Core 2 Duo E6750 (2 Core Load) 163 Watts
Intel Core 2 Duo E8400 (2 Core Load) 158 Watts
Intel Core i7 920 (8 Thread Load) 213 Watts
AMD Sempron 3600+ 148 Watts
AMD Athlon64 4000+ 172 Watts
AMD Athlon64 FX-60 (2 Core Load) 196 Watts
AMD Athlon64 X2 4800+ (2 Core Load) 173 Watts
AMD Athlon64 X2 5000+ (2 Core Load) 207 Watts
AMD Athlon64 FX-62 (2 Core Load) 235 Watts
AMD Athlon II X2 240e (2 Core Load) 153 Watts
AMD Athlon II X2 250 (2 Core Load) 163 Watts
AMD Athlon II X3 435 (1 Core Load) 149 Watts
AMD Athlon II X3 435 (2 Core Load) 166 Watts
AMD Athlon II X3 435 (3 Core Load) 183 Watts
AMD Athlon II X4 620 (4 Core Load) 195 Watts
AMD Phenom II X3 720 (3 Core Load) 213 Watts
AMD Phenom II X4 955 (4 Core Load) 236 Watts
AMD Phenom II X4 965 (4 Core Load) 264 Watts

Appropriately the AMD Athlon II X3 435 test system draws slightly less power (183W) than the AMD Athlon II X4 620 (195W) with all cores stressed. Compared to the Phenom II X3 720 Black Edition, the Athlon II X3 435 based PC draws ~30W less, showing just how much AMD has done to reduce power consumption in the past year.

AMD's first triple-core processor was the AMD Phenom II X3 720 Black Edition. The "720BE" was a 2.8GHz processor with 6MB of L3 cache and an unlocked multiplier, it become quite popular thanks to a combination of competitive pricing and overclocking potential. It's been about a year since PCSTATS overclocked the "720BE" though, and AMD has added another triple-core CPU to its mainstream processor line up. Overclocking is up next!
