News AMD beats Intel in mobile gaming despite new and refreshed CPUs — Ryzen 9 7945HX3D prevails over the Core i9-14900HX in new review

[TerryLaze]

The TDP for this chip is 55 Watts (Base Power). Efficiency after this point begins to fall. (note, it is not in a linear fashion either).

The "Max Turbo Power Value" is the most the ENTIRE Processor can handle, including the iGPU when the CPU and iGPU are running at the same time.

Statement from Intel's Website:

"Is power consumption measured separately for the processor and the integrated graphics controller?
TDP is calculated assuming core and graphics combined, but it's also reported separately for the core and the graphics."

"How can I check the TDP of my Intel processor?

• Go to product specification site (ARK).
• Enter your processor number.
• Under Performancesection:
  • Check the value of the TDP field for processors older than the 12th Gen Intel® Core® Processors.
  • Check the value of the Processor Base Power field for 12th Gen Intel® Core® Processors and above."

Notice how they say the "BASE POWER" is the TDP. Which for this chip is 55 watts. Sure, the Entire Processor can handle more; (and at a huge cost of Efficiency, because anything after that is Turboing)

Have you actually done what they say?
Did you go to arc to see what they say about the 14900hx? They state both the base power and the turbo power, both of them are TDPs, one for base and one for turbo.

Processor Base Power 55 W
Maximum Turbo Power 157 W

Yes I did. And yes, one can use up to 157 watts (even more actually), but the moment the chip uses more than 55 Watts, that's when efficiency starts to go out the window.

And I mention Turboing, because after 55 Watts (it's true TDP,), it's up to Laptop Manufacture to set the Power Limits and their Times, how they Power Up and Down to those Power Limits, etc...

This is why we see the 13000HX have score between 24,270 and 32,623 on Cinebench R23. NONE of those scores are of Intel's responsibility; so therefore, it is senseless to try to figure out who has the "better chip" between AMD and Intel when they are in a Turboing state.

This is where desktop X3D shines, efficiency.

Meteor Lake iGPU vs. Phoenix/Hawk iGPU is the real fight.

and that fight is being lost by Intel lol

From what I've seen they are pretty close, but the results can be highly dependent on things like the memory, since these iGPUs are bandwidth starved. AMD will take back the lead and maybe hold onto it with Strix Point if Arrow Lake doesn't improve.

That would probably require either a lot of cache (maybe even a reduced 32MB 3D cache) or some improvement beyond the current fastest LPDDR5X
