Higher voltages don’t necessarily equate to higher power consumption, but in many cases there is a correlation. Different motherboard models do not apply the exact same core voltage either. The same processor often run at slightly different operating voltages whichĬan affect energy efficiency. Of the processors tested today as sort of a disclaimer. To figure out for yourself if you really want to.īefore we jump into our test results, please note the operating voltages We won’t go through the math it’s easy enough We extrapolate the DC power output from the measured AC power This data is enough to give us a very good estimate of DC demand in our Photoshop: Image manipulation using a variety of filters, a derivationīenchmark V3 (test image resized to 4500×3499).HandBrake: Encoding a XVID AVI file with H.264.TMPGEnc: Encoding a XVID AVI file with VC-1.iTunes: Conversion of an MP3 file to AAC.
#INTEL CORE I5 2400 TURBO BOOST ARCHIVE#
#INTEL CORE I5 2400 TURBO BOOST WINDOWS 7#
Windows 7 operating system – Ultimate, 64-bit Ideally we would run i5-2400 at the exact same voltage/speeds as the i5-2400S, but we weren’t able to match its odd Turbo Boost multipliers (+8, +7, +3, +1). It’s a simple thing to do, and may be a worthwhile alternative if it gives us similar results. To make things interesting, we will also undervolt the Core i5-2400 to approximately the same core voltage used by the i5-2400S by setting an offset voltage of -0.090V on our Asus P8P67 test board. The i5-2400 undervolted to the same core voltage as the i5-2400S, 1.080V according to CPU-Z. It turned out to be US$93 for AM3, US$119 for LGA1156, and US$139 for LGA1155.
In the table above, we added the street price of the chips we’re comparing today with the average price of a compatible motherboard from Newegg (we chose Intel/Asus/Gigabyte/MSI DDR3 microATX and ATX models, omitting the most expensive/extravagant ones). You can’t discuss value without including motherboard cost, which varies from socket to socket. The CPU cost is only one part of the equation.
This is a huge advantage compared to the i3-2100T which trails the i3-2100 by 600 MHz in all loads. This means the i5-2400S will only be slightly behind the i5-2400 in speed much of the time. The i5-2400S gets much larger bumps, 800 MHz for one core, 700 MHz for two cores, and 300 MHz for three cores. The i5-2400 has typical Turbo Boost speeds, overclocking by just 100~300 MHz depending on how many cores are active. The more intriguing part is the i5-2400S, as it is supercharged with very high Turbo Boost frequencies (this couldn’t not be done for the i3-2100T as i3 chips lack Turbo Boost altogether).
