Alder Lake-S leaks

Ok, i have scanned through it.

Blender scores.

5800X: 832
12700KF: 636 (+30%)

Power, This is system power, i don't know what the baseline is but the 5800X like the 5950X uses around 130 Watts, this according to Steve Burke.

So a baseline of around 100 Watts deducted from the result

5800X: 225 Watts (125 Watts CPU)
12700KF: 279 Watts (179 Watts CPU)

179 / 125 = 1.42 (+42%)

So the 12700KF is using 42% more power for 30% higher performance. The efficiency is on the 5800X side.

The 5800X is the least efficient of all the Zen 3 CPU's, the most efficient is the 5950X, it uses 221 Watts in the same test, so 121 Watts for the CPU. the 5900X is using 242 Watts, take off 100 watts for the system and your on the 142 watt limit for the CPU, wow, how that's all worked out.... :)

12900K vs the 5950X.

5950X: 477 (+12%)
12900K: 535

While using in watts:

5950X: 121
12900K: 255

the 5950X is 125% more power efficient than the 12900K, two and a quarter times, that's huge. And if Steve said the 12700KF is more power efficient than the 5800X he needs to check his maths, it isn't.

Just as well nobody in here cares about Blender, then lol

I was challenged on the 12700KF being "more power efficient than the 5800X" without even doing all that maths i knew that was wrong.

Next time don't listen to Steve from hardware Unboxed. :)

He straight up says in the video that the 12700KF is more efficient than the 5800X (why are you pulling numbers from all over the place and bringing the 12900K/5950X into this??)

24% more power but with 31% more performance.

Because the 12700KF is using 42% more power for 30% higher performance.

Check my maths if you like or just move on, either way don't listen to Steve from Hardware Unboxed.

Definitely watch it. The 12700KF makes even more sense than ever before. Power efficiency and performance both on its side. A total no brainer really but like he says at the end, it would be a tough split choosing one platform over another but the 12700K/KF just edges ahead for productivity combined.

If it's for mostly gaming then either side is a winner. Whatever GPU you have will be bottlenecking the CPU platform now. Even a 3090 is too slow for these chips.

This is rubbish, that's not how bottleneck works, it will depend on the application/game, a 3090 will absolutely keep up with any intel at 1080p, specially with its driver overhead issue lol.
 
All this is detracting from the fact that the 12700KF IS a very good CPU, i agree.

But FFS lets keep it real....

You're using the system power figures for the 5800X from one person and the 12700KF system power figures from someone completely different LOL. Nice try.

1? Try 10!

The best one was the meltdown he with the RX 480. He was convinced (based dodgy rumours from WTFtech and the likes) that the 480 would be a lot more powerful. He argued all the way until the end, so much so that Gibbo had to step in and sort it out as they had the cards on hand before release and had a chance to bench it. Was hilarious, will never forget that, he scored like 5 own goals with just that incident there :cry:

Nah. Just saying, you could do with being more objective once in a while you know. Defending AMD the way you do makes people want to buy Intel. Just the way when I see Dave and others doing it for the other side puts me off Intel. But in the end I just ignore it all and buy what is best for me and I am glad I went the AMD route a couple of years ago. Went from 3600 to 5900X and still have an upgrade path if I wanted to upgrade next year (probably won’t though as no need).

I can’t be any more objective. I know it hurts people feelz sometimes but I don’t hold a grudge ;)
