I have no idea how you guys think AMD dominates the mid-low end market. Everything AMD has Intel has a similar price equivalant thats stronger. Intel's also overclock higher everytime, but typically clock for clock intel is faster anyway on all it's equivalents.
Case in point-
Athlon II 250 VS E5300
Phenom II 555 VS I3 530
Phenom II 965 VS I5 750
Phenom II 1090T VS I7 930
In every case here, the intel can overclock higher, is WAY faster in single threaded apps, and will win clock for clock in 99% of multithreaded apps.
The only thing AMD has on intel is the Athlon II quads, which aren't that great for gaming because of the lack of L3 cache. And honestly, I'd rather have an I3 than an Athlon II quad anyday.
Lets See here.
Athlon II 250 VS E5300 -> Yes, intel wins this one in speed. However then you factor in that 775 is EOL, 775 motherboards cost more feature for feature, and AMD starts to become the better value. Plus i've seen some great overclocks from both of the chips, in this case i wouldnt really consider the E5300 to be a better overclocker. Check CPU-Z for both chips on hwbot, the athlon II 250 has higher CPU-Z validations.
Phenom II 555 VS I3 530 -> In that scenario, sure intel wins. How about perhaps the Athlon II X4 630 though, which will beat out the I3 530 in any multithreaded app.
Phenom II 965 VS I5 750 -> Not really processors that i would consider low to mid end, starting to get a bit higher end so intel obviously is gonna win there. As far as overclocking though, on HWBOT the top Phenom II nets nearly 1.5Ghz higher clocks than the i5 750.
Phenom II 1090T vs I7 930 -> Not to mention the fact that the 1055T overclocks just as well, yet is $100 less than the 1090T, i'd say AMD wins price/performance. Not to mention that in any heavily multithreaded app the 1090T outperforms the 930. Also the fact that AM3 boards are far cheaper than 1366 boards. This is one case where AMD shines at the higher end. And again with overclocking, take a look at CPU-Z validations on HWBOT, higher clocks than the intel 920 or 930.
Which, reiterates the point that AMD is better in the value sector. Especially considering the fact someone can go out and buy an AM3 Sempron and a cheap motherboard, and when they get the cash drop in a 1055T hex core. With intel you have no such option in the value sector because of how they like to have multiple sockets. And yes, i know the HWBOT CPU-Z validations i used as source in overclocking were under dice/LN2/lhe, however you simply stated overclocking, which would include extreme overclocking. On air i have seen both chips net similar results to each other, although intel does take the edge on air. Soon as you get into sub ambient though, AMD processors really start to shine.
