first generation core i7 (960), 45nm, october 2009, 263mm^2 die area, 4 cores, 4 threads, 3.2-3.46ghz 731 million transistors, 130W TDP, tenth generation core mobile i7 (i7-10875H) 14nm, Q2-2020. 25mm^2 per set of two cores[0], 8 cores, 16 threads, 2.3-5.1ghz. 43 million transistors per square mm[1] -> over 4.3 billion transistors, 45W TDP. So you have 4 times the threads, at a hair under twice the speed (without stressing turbo boost that much) at 1/3rd of the power at the wall. from top of the line desktop CPU in october of 2009 to "it's ok" mobile CPU from april of this year. Intel stopped publishing (where i can find it) die size or transistor counts, i found the [0] and [1] information on a comparison between TSMC's 7nm fab runs and Intel's claimed 14nm fab runs; and i was only able to very briefly confirm this for the mobile i7 tenth gen and not the desktops. The desktop CPUs are like 400mm^2 larger in physical size, no idea about die size. Sorry. Intel stopped publishing those i guess, seems around the time that ryzen came out or slightly before. edit: 11 years is 5.5 doublings of transistors IIRC, so you should really compare like to like, but i don't have that much free time. My laptop's CPU has 7.8 billion transistors just for the cores, and an additional 2 billion for I/O. sorry. this information isn't in a precise place and i am unused to HN forms. |
