Intel Alder Lake Doesn't Look Like an Overclockers Dream
Another day, another Intel Alder Lake leak, although this time it seems to be the same Core i9-12900K retail CPU that is being tested in China. Some additional details have been provided on its ability to overclock and although it's perfectly possible to overclock these upcoming CPUs from Intel, it's going to be hard to cool them, even for very small gains in clock speeds.
An all core P-core overclock, with the E-cores at default requires quite the Voltage bump as well, since according to the leaked information, going from 4.9 GHz and a power draw of 233 Watts, with a CPU Voltage of 1.275 V to 5.2 GHz, sees a jump of almost 100 Watts. The CPU Voltage also has to be bumped to 1.38 V in the sample used. However, pushing the CPU to 5.3 GHz requires 1.44 V and pushes the CPU power to a massive 400 W, which is high-end GPU territory. That said, we're hearing that not all CPUs need this high Voltage to hit 5.2 GHz, although we also understand that 5.3 GHz is not a speed that will be easily attained. Apparently the best way to get the most performance out of these news CPUs will be to tune the turbo settings, rather than to try and overclock them.

It is a nightmare to cool down... Those who will state that the power doesn't matter as long it delivers speed don't understand how hard to sustain it really is. Like real world usage could be something different, synthetics will like this CPU and it will look better than AMD... but in reality? Well well well
Its a A6 6400K @ 5.7 GHz, 1,625v :twitch:
But its useless its still slower than a A8 5500 :sleep:
Really no one cares if some ppl is trying to make intel look bad. I would be more interested in undervolt numbers, stock clocks and go as low as possible on voltage, or even 100mhz less.
I dont care if the cpu has 3% more performance using 300 or 400 watts, irrelevant to me. Plus, we dont buy CPUs to run Cinebench, Aida or any other useless benchmark all day long. Show me a single game using 225w even
Just wait for that bullzoid or frame chasers guy to make a 50 minute vídeo rambling about motherboards and telling you need to spend 400€ if you want to use a 12900k, like if anyone would need such a vrm
Boring
Edit: I work with my 7870K and GPU Power is more needed than cpu on Solidworks, a I5 10600 is a lot slower in simulations :toast:
Then l, like you, I always undervolt my hardware. Cpu and Gpu. Using less power, less heat, for same performance (more performance on the gpu side).
I run my 10500H at 100 milivolt undervolt offset, underclocked to 3200 MHz and I pretty happy. I get decent performance for 35 watts. Fast enough and cool enough to actually be a lap top.
But I will tell you what is boring.. AMD and Intel fans calling each other shills, pretending wattage ain’t no thang.. and undervolting.. ugh :D
:shadedshu:
:shadedshu:
Nnow entire sure how much of this will be true at time of release, reviews will tell all in the end.
And... undervolted aswell
I didn’t pledge allegiance to them or Intel though.. I have more Intel systems than AMD’s..
But honestly, if you are bored with hardware news take up a new hobby for awhile. I stepped away for a few years to play with other toys too.
(PS: I Have one of these [ZM-MFC3] and my Ryzen + 1070 never went over 350W Total)
