Intel Panther Lake with Arc B390 takes on AMD Ryzen Strix Halo and GeForce RTX 4050 in our first gaming benchmarks

[Redaktion]

Intel Panther Lake promises a massive leap forward in terms of efficiency and iGPU performance. Our gaming benchmarks now provide first insights into how the brand-new Arc B390 iGPU stacks up against the AMD Radeon 890M, Ryzen Strix Halo and against dedicated Nvidia GPUs.

[Dear Author]

Please state the power draw. I'm gonna presume it uses around no more than ~50w when gaming as that's what other benchmarkers have reported.

[Energy efficiency?]

AMD's powerful Ryzen AI Max+ 395 with Radeon 8060S is twice as fast at times, although the chipset is also larger, more expensive and less power efficient.

Just as said:

Exactly. Strix Point is a 256-bit (quad-channel / 4*64-bit per channel), 256 GB/s, APU, while Panther Lake is a 128-bit¹ (dual-channel / 2*64-bit per channel) APU, so it's unsurprising.
Panther Lake: 153.6 GB/s = 128-bit * 9600 MT/s / 1000 / 8.
Strix Halo: 256 GB/s = 256-bit * 8000 MT/s / 1000 / 8.

So, Strix Halo has a 66% higher memory bandwidth.

But if Intel prioritizes the iGPU performance (which I hope they do, because I'm a gamer), it may come closer in gaming performance to Strix Halo, than what Strix Halo' 66% advantage would suggest.

-17%

The Arc B390 being -17 % slower than a 4050 Laptop in Cyberpunk is, on one side, not too bad, but on the other, it's a 4050 Laptop we are talking about, which is like the slowest (RTX 40 series) dGPU out there.

+69%

The Arc B390 being 69 % (nice) faster in Cyberpunk (basically a GPU-bound benchmark) than the 890M is very nice, this is like 2 full node jumps, if only the power efficiency has also on the same level, then this would be kinda crazy (I mean it's Intel's 1.8nm node after all, so it would make sense).

Please state the power draw.

Yes, how much energy was used? Asking the real questions. Guess we'll have to wait until full independent benchmarks on the 28 January where everything is allowed to be tested/revealed.

Will all that said, [..]

With?

[Energy efficiency?]

If

Panther Lake: 153.6 GB/s = 128-bit * 9600 MT/s / 1000 / 8.
Strix Halo: 256 GB/s = 256-bit * 8000 MT/s / 1000 / 8.

So, Strix Halo has a 66% higher memory bandwidth.

is correct:
In the Cyberpunk test, Strix Halo performs not 66 % faster, but 106%..interesting.

[Citizen_not_Consumer]

These benchmarks show that the performance gap between top panther lake and strix halo is larger than I thought at 100%.

Also the statement that Halo is more expensive and more power hungry is not entirely correct, since the HP Ultra Ga laptop is limited to 55 watt total package power and costs double that other Halo offerings.

Also does anyone know the price of the Lenovo laptop with the top panther lake? How the author says it is cheaper??

[Alex]

AMD Radeon 890M is in an disadvantage here because the laptop it is tested on is with the slow DDR5-560 memory.

[please_fix_it]

while Intel Panther Lake can do gaming and others power demanding tasks, it wasn't design for it - those CPU's were design to be in the thinnest laptop and handhelds with minimum while using the minimum watts,

If you want to compare, limit all computers to the same power limits, or wait for the performance CPU's (with 8 or 12 P cores - unlike those H CPUs with only 4 cores)

just for reference, the "HP Z2 Mini G1a" (with Ryzen AI Max+ PRO 395, Radeon 8060S) in this comparation consumes 195.1 watts for Cyberpunk 2077 ultra with Load Maximum of 245.4 watts acording to this site,  while the laptop "Lenovo IdeaPad Pro 5" (with the new Intel Panther Lake use power adapter of 65-100 watts),

why wont you try run a comparation with the PCs limited to 17W-30W for the all CPU+GPU, if you do Intel Panther Lake would probably win most of the test - and I'm not sure if Ryzen AI Max+ PRO 395 could even run properly- because it wasn't design for those power limits...

If I would summary what I want to say: - those CPUs were design to work for different purpose:-

Ryzen AI Max+ PRO or CPU+ RTX4050 - for 80+ WAtts
AMD Ryzen AI 9 HX (like 370\470)  - for 54-80 Watts
Intel Panther Lake                - for 17-38 watts (it can run with higher average but with minimal performance improvement)

BTW, the price of  Intel Panther Lake would probably be cheaper than Ryzen AI Max+ PRO (still can't find a laptop for less than 3000 USD)

Not accurate:
HP Ultra g1a laptop with 395 Halo is operating at 55 watts total cpu+gpu, Asus Z13 flow with 395 Halo depending on the profile, between 30-70 watts.
Also Z13 Halo is around $2000 and newly announced Asus TUF A14 392+8060s will be below $2000 plus several chinese designs e.g. SixUnited XN77 Laptop and table Halo designs.

Top panther lake here 388H with iGPU there is no way products to run at 17-38 under stress. Expect top halo sweet spot around 55 watts long run (under stress), and 80 watts short bursts.

while Intel Panther Lake can do gaming and others power demanding tasks, it wasn't design for it - those CPU's were design to be in the thinnest laptop and handhelds with minimum while using the minimum watts,

Of course it was designed for gaming. That's been the biggest focus of the launch event. A lot of time was spent designing a the larger iGPU that standard PTL-H doesn't have. It was just designed to do these things within a cost structure and design (see same motherboard as the rest of PTL) that meets what OEMs are asking for, as well as a power budget to not compromise on the daily use battery life of the device.

If you want to compare, limit all computers to the same power limits, or wait for the performance CPU's (with 8 or 12 P cores - unlike those H CPUs with only 4 cores)

That'll be part of the full reviews in a couple weeks, but there are no 12P core chips coming out. Not that that actually matters for gaming. Darkmont is more than capable enough to be the 5th+ core when gaming. Any higher end chips than H series are just desktop chips (which since there is no desktop PTL, there is no PTL-HX), but those come with their own issues (worse battery life, larger heavier cooling) that have kept them as a niche for years now.

[Allegedly]

Yeh, the top end 8060S halo config in a NUC form factor with unlimited power is a lot faster.

For those unaware, if you type in "8050S" in the add additional device search box, you can get results for lower tier strix halo config in laptop form factor. And to save anyone else time, it's about 63 fps on a zbook ultra g1a while using ~100 watts in cyberpunk. This I believe was tested while connected to charger (they don't usually tend to test gaming on battery power), so on battery mode with reduced power limits, the results will be slightly worse than that 63 FPS result, I'm guessing.

HP Ultra Ga laptop is limited to 55 watt total package power

I think you're right, on battery it does limit to 55w. But most people don't test on battery either so there's that as well.

All I know is last time I had this laptop, the battery wasn't great and it got quite warm during gaming.

I'm expecting this to be better since they're claiming lunar lake efficiency (which we know is best in class for x86) but obviously we'll have to wait for further tests on this.

Also does anyone know the price of the Lenovo laptop with the top panther lake?

Yoga Slim 7i Aura Edition should be starting $1499. Not too sure on the exact config but I assume it's one with 32GB and higher tier chip because companies like to sell their overpriced stuff first before releasing their more budget mainstream offerings.

Lenono thinkpad with Ryzen HX 370 has ddr5 5600 ram, with LPDDR5x 8000, 890M should be 10-15% more performance. Also, with Ryzen HX 470 with LPDDR5x 8533 and with 200 mhx bump in gpu freq 3100 mhz the gap will be less. I think HX 470 should deliver 30-32 FPS in same test.
Panther lake still wins because HX 470 is a dud update.

No need to compare with any laptops. The fastest implementation of the 890m to date comes from ROG Xbox Ally X so just use that as a point of reference for how the average future Gorgon Point laptop will perform.

It's the best because strix point by design is unbalanced. Too many cpu cores for a small igpu. But the Z2E somewhat resolved this as it's 8 cores instead of 12. Also likely is the most efficient rdna3.5 APU making it interesting to compare against efficiency wise.

[TSGames]

In general pretty exciting it this would find its way in handhelds to acceptable prices. Having xess as upscaling would also be a great win over current FSR2.
Now let's just hope Linux driver support will be good.

[Good point]

Good point, when comparing, it should be noted, whether it's 5600 MT/s unsoldered SODIMM vs soldered LPDDR5X-8000 on the Strix Point/Halo (tho, I haven't seen any SODIMM Strix Halo configs yet) APUs.

Please state the power draw. I'm gonna presume it uses around no more than ~50w when gaming as that's what other benchmarkers have reported.

In video he says benchmarks in this video using 25W.
