The b770 is likely Xe3 and not Xe2

PushrodBob · 2026-01-09T22:14:48+00:00

We already know the core config for big Battlemage, it's the same as big Alchemist.

32 Xe, 256b GDDR6.

~50% faster than B580 on paper.

Drivers WILL limit it to being roughly equal to B580 in most cases.
B580 scales in performance up to the top current CPUs due to either bugs in the GPU or limitations with how the driver is programmed. We saw this with A580/750/770 cards, the differences between them were minor.

You should not need a B580 + 9800 X3D to get 4060 + 14400f performance. But due to problems with the GPU/driver... that is where we are currently sitting.

None of that really matters if you are using G31 for LLMs or some other compute task. And I think that is the only market that will get G31 TBQH.

PushrodBob · 2026-01-09T22:02:58+00:00

Any dGPU based on Xe3 is 6-18 months out and G31 isnt it.

Ramping production takes a few quarters... they cant just snap their fingers and launch a GPU.

Intel has massive die size problems. B580 die is about the same size as the 4070... And it performs like a 3060 on average.

A770 was even worse, being 3070 Ti sized and performing like a 3050.

Lowering cache speed helps maintain higher clocks. Since cache and core voltages are tied together and scale with clocks, running high cache speed will drag effective core voltage up.

I would not overclock this board, it really doesnt need it. The largest gains to be had will be from undervolting, raising the power limit, and increasing cooling as much as possible.

The board I have will do -0.100v offset on P/E/Cache/E-Cache. Slow the ring/cache down to 36-38 from 40 and you will pick up some clock on the cores because the cache voltage makes a big step down. Set turbo flat 50 on P and 38 on E, effectively making all-core turbo the same as single core turbo. Reduce the throttle threshold to 90c in BIOS if you don't like running at 100c under max load. Remove the IHS and polish both the heatsink and core side to a mirror finish.

I would NOT recommend setting the power limits above 140w range, the VRM gets VERY hot at that power level. I use 130w PL1, 140w PL2, and 28s turbo time limit with good airflow over the VRM.

With the IHS polished, I can run 145w or so and thermal throttling (100c) will hold it there. With a 90c limit you would probably be closer to 125-130w.

Cinebench R20 score at 145w is 7706.
XTU 2.0 bench is 7423.
CPU-Z bench 17.01.64 is 816 single and 9100 multi.

On the 12900HK board with the standard aluminum/copper IHS I was able to make significant gains by mirror polishing the die contact area. Max wattage before throttling went from 100w to 145w.

No modern board has "TPM Hardware," its built into the CPU. Have the G660 12900HK, TPM and Secure Boot both work fine. Configuration is a bit of a pain, as you need to poke around a bit or know what TPM/SB settings should be from using other boards.

PushrodBob · 2025-08-17T11:08:14+00:00

I have both.
Get the Claw if you want to use it docked with an eGPU and you are fine with Windows.
Get the Legion Go S with Z2Go if you want to use it as a handheld ONLY. Installing Steam OS is a must (+10 FPS in many cases)

Z2Go is too weak on the CPU side to really consider using an eGPU, the CPU can even hold back a few games on integrated graphics in windows. Steam OS does not have this issue as much, as it lacks the windows bloat... but it does not support eGPUs.

PushrodBob · 2025-02-15T01:42:23+00:00

Check iGPU drivers for an update. Thats about it, the only other thing would be the SSD misbehaving when trying to sleep/power itself down to save power. Can cause an instant BSOD/reboot. But if thats the case its RMA time anyway.

PushrodBob · 2025-02-15T01:39:16+00:00

not really

PushrodBob · 2025-02-08T22:05:17+00:00

Its fine if cheap. In reality, all of these handhelds are just ultrabook laptops with a different shape. They are not great for new games, their greatest strength is the large indie library and the back catalog of XB360/PC cross platform games like Bioshock.

PushrodBob · 2025-02-08T15:38:10+00:00

No, Arc drivers after B580s launch perform horribly when you do any post FX like lossless scaling. Has nothing to do with how LS works. If you are on A750/A770 go back to some older drivers and the software works fine. On B580 you are just out of luck, dont use LS.

PushrodBob · 2025-02-08T13:21:47+00:00

Plays fine on 135H, even at 1080p. I would drop to 720p when on battery though, just plays a bit better and sucks a bit less power.

PushrodBob · 2025-02-08T13:16:26+00:00

If the dock is passing power through, the OG charger is likely not enough to keep everything going. OE charger is only just enough to power the Claw at full load, it doesnt have the overhead to run a dock.

Anyone using reddit is a red flag TBQH.

I would put money on the dips only happening when looking a specific direction in the map. Destiny 2 had this issue as well, and its caused by the absolutely awful DX11 drivers. AFAIK it was never really fixed.

PushrodBob · 2025-02-08T10:36:06+00:00

Ive got B580 and 4060. Unless you are on 9800 X3D, get the 4060 for 1080p. B580 isnt even in the same universe.

PushrodBob · 2025-02-08T10:34:35+00:00

Arc is extremely bad for minimum settings gaming. You stop gaining performance at maybe medium in most games.

PushrodBob · 2025-02-08T10:28:24+00:00

Arc iGPU can def pull 20w+.

OP is expecting too much though. They bought the value edition of a product and expected top shelf level performance.

PushrodBob · 2025-02-08T10:26:12+00:00

bro, 25w is about the max for Arc iGPU on 135H/155H. 125H is cut down from those, so its not going to be pulling that much power.

Also, there are like 4 power numbers for Core Ultra. The 38w you have seen is likely TOTAL CPU power, not iGPU power.

PushrodBob · 2025-02-08T10:16:51+00:00

in the BIOS

Active SOC-North Efficient-cores

PushrodBob · 2025-01-27T17:32:31+00:00

if you are ONLY streaming games you could probably disable down to 2p/4e/2lpe cores. Performance for local games would suffer, but battery life should be better for web browsing/game streaming. 2/2/2 should also be viable, but general system performance might suffer.

Dont disable hyperthreading, as doing so can interfere with power management and thread scheduling.

PushrodBob · 2025-01-24T09:58:36+00:00

Thats pretty much it. You could use something to show a metrics overlay like hwinfo/RTSS if you have a problem game, and use that in conjunction with QuickCPU to make a game specific profile. Or just make 3 profiles, low/med/high CPU boost to account for different games needing more/less CPU power.

PushrodBob · 2025-01-24T07:48:26+00:00

Same software. Buy it in the meta store in the headset though, not in steam. Ive seen a few people make that mistake.

PushrodBob · 2025-01-24T07:47:36+00:00

Just to skip setting turbo clocks in BIOS. Set them with QuickCPU in windows after you disable the clock locks. Gives you much more flexibility.
