Panther Lake Geekbench Leak (its good!!)

Posted by protos9321@reddit | hardware | View on Reddit | 127 comments

Panther Lake X7 358H is about 1.74x the performance of Lunar Lake in geekbench opencl test

Do note that this should be pre-release drivers/firmware. So by the time of release we could expect more performance (maybe even quite a bit more considering Intel's current driver situation)

I have a few thoughts on this. There seem to be 2 big takeaways from this

  1. Panther Lake performance

  2. Asus G14

  3. Panther Lake performance

So Panther Lake 358H seems to be about 1.74x the performance of Lunar Lake 288v. Based on Geekbench scores on opencl. Panther Lake 358H is approx 1.74x Lunar Lake 288v while 4050 Laptop is 2.5x and 8060 is 3x.

I've taken a look at notebookcheck gaming benchmarks for the 140V in Lunar Lale at 1080p high and compared them to the 8060s and 4050 laptop and I got approx 2.5x and 3x the performance for 4050 Laptop and 8060s respectively. So the geekbench scores seem to be a decent indication. Do remember here that the 4050 and 288v are averages of many laptop designs, so some could be lower power whereas the 8060s should only be an averge of 2 designs.

Do note that some of the gaming benchmarks seemed to BW limited and in one case, the 4050 could only manage 66% more performance than the Lunar Lake while the 8060s managed 2.25x the performance.

  1. Asus G14

Intel has never been used in an Asus G14 before, so this is huge. Also Asus is using the 12Xe core config, which is interesting as it would be more expensive than the 4Xe core config.

This either means that Asus thought that the igpu performance was quite important to them or that there's a chance it doesn't have an dgpu. The latter is much more interesting than the former as it would mean that this is the first igpu based G14. Some of you may think that this doesn't make sense as strix halo would be a beter fit. However Strix halo is a terrible product. Its got really nice cpu, a decent gpu that performs 10-20% better than 4050, however a stix halo laptop could cost as much as a 5070ti laptop and somehow have worse battery life than the 5070ti laptop despite having only an igpu. Panther Lake could cost half of the strix halo, while having 2x the battery life and higher single core performance. Multi core and gpu wise it would still be considerably lower than strix halo, but again it could be almost half the price. Would you pay for a hypothetical strix halo G14 which costs the same as the 5070ti model but half the gpu performance (even if the multi core performane is 40% higher) and worse battery life?

If you look at perf per dollar the 5070ti model would still be better, but at around 1200-1300$ which I think they can price at (remember PTL is cheaper for Intel to make than LNL), there really isn't any better premium laptop soc. This could compete with the macbook air, dell xps (I dont remember its new name), yoga pro 7i and others and also create a design for future igpu only performance laptops for Asus. At the end of the day this is still speculatiion but its possible..

Overall with all the improvements to Xe3, memory bandwidth being increased to 153 Gbps and the fact that Lunar Lake could only use 80Gbps of the 135Gbps of memory bandwidth (https://chipsandcheese.com/p/lunar-lakes-igpu-debut-of-intels), I think that there's enough BW for Intel to easily push 2x the performance. Infact considering the 50% in size and the 25% higher clocks even a ipc uplift of around 10% is enough to provide performance that is 2x higher than Lunar lake. We'll just have to wait and see if they can do it.
