Although true, we must not forget that you also need new, specifically-coded real-world software to take advantage of the real-world performance gain.
without a dedicated graphics card, amd 7850k wins miles over intel i5
The AMD's R7 250-based IGPU will be better. It's even about 3% faster than the Iris Pro 5200 in gaming.
Being a gamer I will still go with Intel, especially since emulators require such ridiculous power per core. However I love the direction AMD is moving towards, in a few years there really won't be a reason to pick intel once AMD's IPC is "good enough" and their integrated video is also "good enough". For mid to high end gaming.
at Micro Cneter Here is Ohio they have the A10 7050K for 149.99 and get 30$ off on a selective motherboard with the I5 4670K they have it for 179.99 and 30$ to 40$ on selective Motherboards i went with the I5 because i have always used AMD so i wanted to Change up the Computer this time and try a Intel and so far i like them both it now just depends on what you price range is and who you like the most i thing about 10 year i will just build a new Computer and use all AMD
might not be gpuboss, but since they both have integrated graphics it is important to show which is better with gaming also
errrm...this kinda isn't gpuboss
Graphic benchmark test ?
And remember the A10 uses the new HSA Tech. so to really see what it can do you can't really rely on these same old run of the mill pick and choose benchmarks anymore
Where's the price for the A-10? Odd....
