AMD A8-3870k vs A10-5800k

post #1 of 50
Thread Starter 
Hi guys! I really need help over here. I want to buy ASAP a new pc, and it will be APU!

I have seen various tests, like in toms hardware, but they are inconclusive and untrustworthy for a simple reason: they compare using different clock speeds.

As you can see in the particular test, they have left the new trinitys with the turbo-core enabled, so the 5800k runs about @ 4.1~4.2GHz, and not @ 3.8.As you can see in the various tests, llano, considering the clock difference, is a little behind trinity, and in some cases has the lead. Adobe, i-tunes and sandra are to be excluded because they are not benchmarks at all, at least for me

The only big obstacle for me is that if I get llano, i get a dead socket, a dead motherboard.
The only good thing in trinity might be its gpu, but consider that its 200mhz faster than llano's, and 200mhz in top of 600mhz is not a small number..

So whats your opinion in this? Forgive me for being rude, but don tell me about the "per watt" cap, they dont apply for me.
Is there anyone in this site that can make a clock to clock, core to core test (underclocked 5800k @3ghz without tubo-core vs 3870k @3ghz)???

From my perspective, trinity is crap; Why on earth do I need more ghz to have almost the same performance as llano with fewer ghz?

Lol. Which one performs better? Trinity. End of thread. That's all that matters,no brainer here.

Why do u care about clock-to-clock tests. Nobody is gonna downclock the trinity CPUs in real life.... trinity preforms better. thats all there is to it

Lol, based on what??? Where is your justification?

Clock to clock shows the difference between those two. I m never gonna downclock a trinity; justt to see the difference.

the a10 5800k. higher stock speed, faster architecture, faster igpu ect
EDIT: also, you said you would end up with a dead socket, and it is faster clock per clock, and even if it was = clock per clock, what makes you think you will be able to overclock a llano as high as a trinity? most people hit the wall at 3.6ghz without igpu.

They maybe near in some x86 bench, but just for the igpu + lower power (better OC?) Trinity is a way better choice for me. Besides, Fm2 seems to be compatible with next gen apus. Who cares about the IPC if the overall power is better?

Your basing too much on instruction per clock, which alone matters nothing. What you need to consider is instructions per second potential, and power consumption. Trinity may not have reached llano in ipc, but it easily clocks much higher at the same power consumed. Therefore Trinity is the better processor. Not to mention the igpu is better.


Incase that just blew over your head... lets say this.

a 1ghz processor with high ipc renders a video in 1 minute consuming 95w, and it's average overclock reaches about 1.2ghz, increasing it's capabilities and it's power consumption.
a 2ghz processor with lower ipc renders a video in 45 seconds, consuming 80w, and it's average max overclock reaches about 2.6ghz, increasing it's capabilities and power consumption

Now the first processor seems nice with it's higher ipc until you find out it can't nearly keep up because of clock limitations. while processor 2 already surpasses it's sister at their stock clocks, and can go even further. This is how you should view trinity.
