When you start to scale performance, the core starts to matter a lot less. A standard 95w desktop processor has the TDP to push clocks much higher. It has the TDP to add loads of extra cache and reduce those misses. It has extra memory channels and the memory can operate at higher speeds. It has much more RAM reducing HDD read penalties.
When you start scaling out cores, interconnect starts to eat a huge amount of the power budget. All the extra PCIe and other IO eat even more.
When you start to ramp up into the 3+GHz clockspeed range, things start to get really hard and you have to make IPC tradeoffs.
The idea that a 5-10w A12 beats the performance of a 95w x86 processor is talk from a place of extreme ignorance.
Add all the features even a workstation laptop chip has and the A12 will start to struggle just like every other architecture does. There's no magic in chip design. There aren't really big competitive edges to be found anymore as all the low-hanging fruit has already been picked a decade ago.
- ksec 8y agoWhen the word Desktop is used, most would assume it means vast majority of Desktop, not Prosumer Desktop, Gamer Desktop ( Despite a huge amount of sales are coming into it now ) or Workstation Desktop. And I can assure you most don't have have Quad Core, or even Quad Thread, let alone 32 Core. Most don't have more than 8GB Memory. And my guess is the OP was using the word Desktop as being PC, Laptop + Desktop. I am just guessing but He should have been more clearer in that.
- hajile 8y agoThat's just moving the goalposts and is a non-argument. A 13" ipad pro starts at $999 and goes up over $2,000. Any desktop in a similar price range will stomp the ipad processor without much issue.
- ksec 8y agoMoving Goal Post? No one buys $2000 Desktop anymore. Majority don't. And you had to pick the most expensive 0.1% Market Desktop compared to A12X. The A12X here is a specific comparison, while the words "Desktop" is an generalisation. When I say my X Bike is comparable to Road Cars, Road Cars here means everyday cars, not your Lamborghini or Ferrari 455. Which we ALL KNEW would be faster than this Bike anyway. But you had to nitpick on the word "Desktop". And then decide to use Similar price range as an argument which was never the intention nor what we started to compare it with.
