iMac 21.5 MC508

Introduction Date: July 27, 2010 Discontinued Date: May 3, 2011<br> Processors: 1 (2 Cores) Architecture: 64-Bit<br> Geekbench 2 (32): 5681 Geekbench 2 (64): 6356<br> Geekbench 3 (32): 1909 Geekbench 3 (32): 3966<br> Geekbench 3 (64): 2026 Geekbench 3 (64): 4344<br> Processor Speed: 3.06 GHz Processor Type: Core i3 (I3-540)<br> Details: This model is powered by a 32 nm, 64-bit Intel Core i3 "Clarkdale" processor with dual cores (two independent processor cores on a single silicon chip). Each core has two threads, for a total of four threads for the system, as well as a dedicated 256k level 2 cache. The processor cores share a 4 MB level 3 cache. It also supports Hyper Threading, but does not support "Turbo Boost" -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the two cores it will automatically increase the speed of the core in use and turn off the unused cores). <br> Also see: How much faster are the "Mid-2010" Aluminum iMac models than the "Late 2009" models?<br> Turbo Boost: 3.06 GHz Custom Speeds: N/A<br> Processor Upgrade: LGA 1156 (Socket H)* FPU: Integrated<br> System Bus Speed: 2.5 GT/s* Cache Bus Speed: 3.06 GHz (Built-in)<br> ROM/Firmware Type: EFI EFI Architecture: 64-Bit<br> L1 Cache: 32k/32k L2/L3 Cache: 256k (x 2), 4 MB<br> RAM Type: PC3-10600 DDR3 Min.
