As you would expect, the Quad-Core model was fastest in the processor-intensive tasks that can use more than two processors at once, namely MathematicaMark (63 percent faster), Cinebench (29 percent faster), and Compressor (20 percent faster). Though both systems slowed down when using the higher resolution, new 2.8GHz iMac still managed a respectable 55.1 frames per second, 35 percent faster than the 40.9 frames per second the 2.66GHz model was able to display.Ĭomparing the new Quad-Core 2.8GHz Core i5 iMac to the other available 27-inch option, the Dual-Core 3.2GHz Core i3 iMac, the new Quad-Core model was 15 percent faster. When running Call of Duty at the 27-inch iMac’s native 2560 by 1440 resolution, the differences between the two card was much more pronounced. Unfortunately, this resolution doesn’t always show the benefit of higher-end graphics. For Speedmark, we use a lower 1024 by 768 resolution to allow us to compare the performance of legacy Macs. In our Call of Duty tests, we saw minimal improvement, a little less than 2 percent. While both use ATI Radeon HD graphics, the new model uses a 5750 with 1GB of GDDR5 memory, while the older model sports a 4850 with 512MB of GDDR3 memory. Looking at the specs between the two models, the biggest difference would appear to be the graphics card.

Interestingly, the only test in which the older model prevailed was in our Unzip archive test, which it finished just one second faster than the new iMac.
The biggest differences were in the iTunes encode test, with the new Quad-Core 2.8GHz Core i5 model finishing 13 percent faster than the older Quad-Core 2.66GHz Core i5 the HandBrake test, with the new model coming in 26 percent faster and our Parallels WorldBench tests, with the new model completing the task 21 percent faster. Also, be aware that this 32GB max is reported only to work with the i5s and i7s, not the i3s or the older Core 2 Duo processors which max out with 16GB Ram at 1.5V setting.Results were very similar between the two Quad-Core models, with just a few seconds separating them in most cases. So look up the serials on the manufacturer or vendor website that lists the specs and go from there. In this case, the 1333 Mhz speed is what is reported. Issue is not with higher speed memory which just defaults down to the lower speed that the BIOS supports. Samsung, like Crucial, Elpida, Kingston, Corsair, etc all make good memory, but even the best memory will not work if it is does not support the correct voltage type. So, some people will report Samsung as working, and others will say it does not. Trick is to make sure the memory you get supports 1.5V as most of the newer memory is lower voltage (eg., 1.35V or 1.2V) that is NOT SUPPORTED by the iMacs older than 2013. Memory under "About this Mac" is reported as "32GB of 1333 Mhz DDR3." Therefore, not reported as its native 1600 Mhz.

Was able to install four (4) mixed serial 8GB SO-DIMMs of Samsung PC3-12800 (1600Mhz) DDR3 SDRAM memory modules (Samsung Memory sticker IDs listed as M471B1G73DB0-YK0 1338 and M471B1G73CB0-CK0 1251) in a Mid-2010 27" iMac with an Intel 2.93Ghz i7-870 processor. "PC3-12800" is the name used in the memory industry - 12800 indicates a peak transfer rate of 12800 MB/s (of course, the actual performance in your case would be brought down to 8533 MB/s, matching PC3-8500).
"1600" is the data transfer rate per second specified in millions (the technical term is "clock frequency") - "1600" here means it supports up to 1600 million transfers per second - in your case, it will be slowed down to 1066 million transfers per second since that's what your Mac is designed for."DDR3" is the type (and must be the same as what your computer has).However, your system will operate at the speed of the slowest memory module. Memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. Here's some relevant information from Crucial on memory speeds (emphasis mine): You could add the 1600 MHz memory for your MacBook Pro even though it's designed for a slower memory (1066 MHz) - it ought to work, but you'd be better off buying from a place that accepts returns.
