Why not a T series CPU?

[ver01@]

Seems that new games benefit from more cores. The 12100 did a good job but time to change. It's a miniITX build so looking for a CPU that doesn't need much power. Would a T series i7 be the way to go?

the T chips are low power and much slower.
what games and at what resolution?

a 13500 would be faster than a 12700t, i managed to keep a 13500 cooler with a very low profile cooler for gaming load.
the 12700t as a max power of 99w the 13500 would sit around 65w in games

 

[ver01@]

Boost speeds are not much different so why would there be a big difference in performance? Looking at some tests and the 13400T if faster compared to 12400 for a similar price.

 

[Wing-Man]

It’s faster when you let it boost for longer and use more watt’s and in that case you may as well just get the 13500 for more cores

 

[ver01@]

When at boost does it use more power than the 12400 or 13500?

 

[Wing-Man]

It would use the same. If you let the 13500 do what’s it wants it will use upto 150w but if you set intel spec it will use about 60 to 80 in games and day to day tasks.

 

[Wing-Man]

The 12400 doesn’t have Ecores. The 13500 dose. But looking now the 13400t dose have a few too

 

[Wing-Man]

You can get the none t chip and power limit i to a set speed / temp of your choice.

Looking at it the 13400t dose look like a nice little cpu. The lower boost would hold you back in single threads games. But it’s only a few hundred mhz

 

[ver01@]

What's the point of the reported TDP assuming you use the same CPU's 12400 and 13400T on the same motherboard with default settings?

 

[Wing-Man]

At default one will boost higher for longer. One will not. On a none T chip it can hold full boost indefinitely. The t chip will follow intel specs and drop its clocks.

The 13400t as 4 more cores than a 12400 and only just manages the same performance. And about the same power usage.

A 13500 as 8 mores cores and you can pick the power limit it but still let it hold full boost indefinitely

 

[ver01@]

Why would it boost for longer if it exceeds temp specs? Don't think you are right but will see what others think.

 

[Wing-Man]

If you set the cpu to stay under 85w in games I would normally see mid 60w so as long as it’s under 85w it will hold boost

For me tuning a none T chip would be better then using a T chip

 

[ver01@]

If the performance/watt is the same then getting a non-T chip make sense.

 

[Wing-Man]

If the performance/watt is the same then getting a non-T chip make sense.

at a lower boost clock, that doesn't hold for as long the performance wont be the same.

the 13400 vs 13400t the none t is about 10% to 15% faster in all tests. and at about the same power usage when intel spec is set.
so moving to a cpu like a 13500 with 4 more cores. when setting a power cap of 85w(same as the T chip) the 13500 is about 9% faster than a 13400(none t) at the same power settings

if you games at 1080p where the CPU is the bottle neck the gap will feel there big

T chips are usually a bad idea for games because of how their lower turbo curbs the single core performance and games always need that (even if they use multiple cores), that's part of the reason the 12100 is a good gaming CPU despite having just 4 cores.

In terms of power, the 13400 is already pretty good, in TPU's review the 13400F had an average draw of just 44 watts when gaming, so the main reason to buy a T CPU is to ensure that the limited cooling capacity of your case/CPU cooler isn't exceeded when the CPU is heavily loaded (which is why SFF OEM PCs are full of T chips).

My motherboard supports cTDP and most other boards allow you to change PL1 & PL2, so you can turn a non-T into the equivalent of a T, without the cap on performance in the future (if you need it).

I fell for the 12700T marketing as a high performance low power chip. The sacrifice is very much the performance. As with everything it comes down to price, if T chip makes sense or not.
