Intel Core i5 750 2.66GHz Socket 1156 Processor Review

Intel Core i5 750 2.66GHz Socket 1156 Processor Review - PCSTATS
Abstract: The Intel Core i5 750 processor is a mainstream quad-core CPU that promises enthusiast-level performance for the masses. The Core i5 750 is part of Intel's most recent generation of socket 1156 processors which include not only the Intel Core i5 700-series but also several Intel Core i7 800-series chips, codenamed "Lynnfield".

Core-by-Core System Power Draw

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.

Given that motherboards vary across these test systems this is not a "true" measure of CPU power draw alone, but rather a measurement of the total computer system power draw, which we can compare for each specific platforms between the CPU idle and CPU stressed states.

Does a two-chip motherboard and a 95W TDP processor make a real difference?

The Core i5 750 processor is one of Intel's most power-efficient mainstream offerings, and thanks to some intelligent power management, it should be able to reach some very low power consumption numbers...

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 i5 750 124 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 250 128 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

At idle, the Core i5 750 system draws about as much power as Intel's Core 2 Duo systems, which have only half the cores. The Core i5 750 is significantly more power efficient than its closest rivals, AMD's Phenom II X4 processors.

Total System Stressed Power Draw - All Cores/Threads

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 i5 750 (1 Core Load) 135 Watts
Intel Core i5 750 (2 Core Load) 146 Watts
Intel Core i5 750 (3 Core Load) 157 Watts
Intel Core i5 750 (4 Core Load) 169 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 250 (2 Core Load) 163 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

Under load it's easy to see just how good a job of taming this four-core mainstream processor. The Core i5 750 system is just shy of a 170W draw when all four of its cores are under load. This is 40W less than the Intel Core i7 920 system, and nearly 100W less than the AMD's Phenom II X4 965 processor!

Overclocking is up next, just how far can PCSTATS take a quad-core that has just a 95W TDP?
