Posted October 17, 2017 What is the difference between i7 7700k and 7740x The only differences I see are socket, TDP and base clock speed. 7740x is also $5 cheaper on pcpartpicker. Also is higher TDP better for overclocking? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted October 17, 2017 cache size is different aswell socket makes a big diff as the mobos differs and in turn features id hope that the enthusiast platform cpu would do better Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted October 17, 2017 Since the 7740x requires x299, you'll end up spending more on a board. The cache sizes also differ. The 7740x is the better of the two but I'm not sure it justifies spending significantly more on x299.

Also is higher TDP better for overclocking? Higher TDP is generally worse for overclocking - it only means more heat that you have to dissipate for cooling (costing more in cooling) Also, the cheapest 2066 motherboard costs about $100 more than a 1151 mobo. The new architecture may have some iicp improvements, but it's not worth the extra cost. Personally, I'd go with a used 7700k. Fan Comparisons F@H PCPartPicker Analysis of Market Trends (Coming soon?

Posted October 17, 2017 7700k is for Z270 boards and has iGPU. 7740X is for X299 boards and lacks iGPU. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted October 17, 2017 Yeah, double checked. PCPartpicker says that the caches are the same. Fan Comparisons F@H PCPartPicker Analysis of Market Trends (Coming soon? Never? Who knows!)

Posted October 17, 2017 Before you go and buy a x299 board, why don't you buy a z370 board with an i5-8600k? The 8600k outperforms a 7700k and is a good overclocker according to some tests. Also it's 40$ cheaper on pcpartpicker. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
