mido Posted November 27, 2022 Share Posted November 27, 2022 If I plug my laptop to an external screen, optimus disables, thus bypassing the integrated intel hd, and getting better GPU performance. Thats normal. What I dont get, is that CPU performance also improves. Cinebench R23 : ~8300 Cinebench R23 (optimus off) : ~8500 (got up to ~8700 with further undervolt, but 8500 score was with the same settings) 3dmark Time spy CPU score: 8500 3dmark Time spy CPU score (optimus off): 8700 (CPU test is just 1fps higher) I get 3dmark cpu score might benefit from the optimus off, because it uses the GPU, but why Cinebench score increases too? I tested like 5 times each bench with opitmus on and off. Laptop is a MSI GL65 10750h + 2070 super Link to comment Share on other sites More sharing options...
Etern4l Posted November 27, 2022 Share Posted November 27, 2022 When active, the iGPU consumes some RAM bandwidth (about 1GBps?). Also remember there tends to be a fair amount of variance in CB23 results. "We're rushing towards a cliff, but the closer we get, the more scenic the views are."

Aaron44126 Posted November 27, 2022 Share Posted November 27, 2022 (Speculation) If you're hitting power limits, the iGPU would also consume some power, so cutting it off could give a bit more headroom for the CPU to just do "computing".

Interesting. Which specific power limits include power consumed by iGPU? @Papusan "We're rushing towards a cliff, but the closer we get, the more scenic the views are."

KING19 Posted November 29, 2022 Share Posted November 29, 2022 Bypassing optimus improves CPU performance somewhat because with the IGP disabled your CPU works a bit less and nothing is bottlenecking it. Also you should monitor your temps when running benchmarks if your laptop isnt throttling because that can affect your scores too The major improvements in by passing optimus is in gaming mostly E-Sports games like CSGO, Overwatch and etc that are more CPU dependent than GPU dependent.

Etern4l Posted November 30, 2022 Share Posted November 30, 2022 Yes, forgot to mention the obvious that in graphics-intensive applications there is also some additional overhead due to rendered data being also copied to the iGPU frame buffer.

raptorddd Posted December 22, 2022 Share Posted December 22, 2022 am trying to play morrowind fors the first time. i have dell m4600 intel hd3000 and quadro 2000m but i cant get it to use the nvidia GPU. tried nvidia control panel tried right click and pick wich GPU to use. this way i had made it work like 2 times. when i disable optimus i get double the fps. in a laptop with no battery is it ok to run optimus off.? dell precision m4600 i7 2760QM 8GB ram MX500 crucial SSD 500GB. win 10 21H2 Link to comment Share on other sites More sharing options...

Yes, Optimus is primarily for power savings. It is fine to run with it disabled, it generally removes some hassle this way. Inability to get the NVIDIA GPU to engage in Optimus after a GPU upgrade is generally a symptom of the INF mod being done wrong. I ran into this myself when I did my first GPU upgrade (Quadro M5000M in Precision M6700). When you do the device ID replacement you have to make sure that you are replacing a configuration that supports Optimus. These Dell systems actually change the hardware ID depending on if Optimus is enabled or not so you have to pay attention to which hardware ID you are replacing to do the INF mod. 2 Dell Precision 7770 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Dell) — Dell Precision key posts • Dell driver RSS feeds • Dell Fan Management — override fan behavior Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10 LTSC Spoiler Dell Precision 7770 (personal) Intel Core i9-12950HX ("Alder Lake"), 8P+8E 8× P cores ("Golden Cove"): 2.3 GHz base, 5.0 GHz turbo, hyperthreading 8× E cores ("Gracemont"): 1.7 GHz base, 3.6 GHz turbo 128GB DDR5-3600 (CAMM) NVIDIA GeForce RTX 3080 Ti 16GB (DGFF) Storage: 2TB system drive: Samsung 980 Pro, PCIe4 24TB additional storage: MDRAID, RAID 0 2× 8TB Sabrent Rocket 4 Plus, PCIe4 1× 8TB Inland Performance Plus, PCIe4 Kubuntu 23.04 (KDE Plasma 5.27, Linux kernel 6.2) 17.3" 3940×2160 120 Hz display Intel Wi-Fi AX211 (Wi-Fi 6E + Bluetooth) 93Wh battery IR webcam Fingerprint reader Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth) 95Wh battery IR webcam Fingerprint reader Previous Dell Precision 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...

Yes, that's what I'm referring to. Normally, messing with the INF file is required for "unsupported" GPU upgrades. I'd suggest that NVIDIA didn't actually turn Optimus support on for whatever system this card is being recognized as (since it is not "supposed" to be working) and it would still require an INF mod to "fix" it properly. Probably easiest to just disable Optimus altogether, if you don't actually use the system on battery! 1 Dell Precision 7770 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Dell) — Dell Precision key posts • Dell driver RSS feeds • Dell Fan Management — override fan behavior Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10 LTSC Spoiler Dell Precision 7770 (personal) Intel Core i9-12950HX ("Alder Lake"), 8P+8E 8× P cores ("Golden Cove"): 2.3 GHz base, 5.0 GHz turbo, hyperthreading 8× E cores ("Gracemont"): 1.7 GHz base, 3.6 GHz turbo 128GB DDR5-3600 (CAMM) NVIDIA GeForce RTX 3080 Ti 16GB (DGFF) Storage: 2TB system drive: Samsung 980 Pro, PCIe4 24TB additional storage: MDRAID, RAID 0 2× 8TB Sabrent Rocket 4 Plus, PCIe4 1× 8TB Inland Performance Plus, PCIe4 Kubuntu 23.04 (KDE Plasma 5.27, Linux kernel 6.2) 17.3" 3940×2160 120 Hz display Intel Wi-Fi AX211 (Wi-Fi 6E + Bluetooth) 93Wh battery IR webcam Fingerprint reader Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth) 95Wh battery IR webcam Fingerprint reader Previous Dell Precision 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...
