Apparently the 4 core xe graphics in the core ultra 5 125u don't have shared memory how much is allo

[allgamesonxeigpu]

I would like to know how much graphics memory is allocated to the igpu on the core ultra 5 125u. Would adding more ram improve igpu performance like it does when the igpu uses shared memory. Does the 8 core version of the igpu 8 core xe arc graphics again an igpu can it play city skylines 2 currently without the yellow screen artifact that currently makes it unplayable on the 1165g7 through 13th gen

[allgamesonxeigpu]

Well it's not really advertised last of us and city skylines 2 were tested on the core ultra 5 125h although it looks like he just loaded a save file so there's no way of knowing if it works the last of us crashed in his testing as well as warzone which is strange since I can play warzone on my 1165g7. I think based on this I'll try buying city skylines 2 again https://youtu.be/q7AaeHxbPw0?si=5o85pnEkItekcqgh

I still don't know if my core ultra 5 125u needs more memory notebookcheck said it didn't use shared memory so I guess the answer is no

Hello ,

Thank you for posting in Intel community Forum.

For us to further check this, please help provide the following details:

1. What is the brand and model of your laptop?
2. Can you provide the system memory of your system?

If you have questions, please let us know. Thank you.

Best regards,

It's an Aoc laptop with core ultra 5 125u processor with 16gb of ram ddr5. I don't have it yet it's being shipped for my birthday. I understand different laptop manufacturers might customize the laptop in different ways but I guess they would still all not have shared memory.

1. What I need to know is does the core ultra 5 125u have shared memory notebookcheck says it does not.

2. You seem to be implying different manufacturers put different amounts of memory on the core ultra 5 125u chip since it isn't shared. Give me an example of one of them please.

Sorry for being such a pain 

[allgamesonxeigpu]

Well I guess it's the aoc mx16 with core ultra 5 125u with 16gb ram

Hello allgamesonxeigpu,

Thank you for the quick reply.

Regarding Graphics memory, let me share this link for additional information:

https://www.intel.com/content/www/us/en/support/articles/000020962/graphics.html

As for the processor, he is the default specification of Intel® Core™ Ultra 5 Processor 125U:

https://ark.intel.com/content/www/us/en/ark/products/237330/intel-core-ultra-5-processor-125u-12m-cache-up-to-4-30-ghz.html

The reason why I say "default" specification is that is the specification provided by Intel when we created the processor. However, when OEM manufacturers install them on their system, they are now being controlled by their BIOS. They can alter, enhance or modify processors, graphics controller, wireless cards and other components depending on the design of the system or laptop. Same with Graphics cards, they can create an OC version of a certain Graphics card. And these changes are unknown to us because that is their own product now.

Like in this case of Intel® Core™ Ultra 5 Processor 125U, in the link that I provided it says the Max memory that it can support is 96 GB. Your laptop is using 16 GB and we don't know if this is upgradable.

If you have questions, please let us know. Thank you.

So the information on this page that says shared memory is no is incorrect? Do you have more detailed technical details than this I always go to that site when researching what chips to buy. Although whether the processor uses shared memory should really be on that page. The old iris integrated graphics way back when had their own memory 

https://www.notebookcheck.net/Intel-Graphics-4-Cores-iGPU-Arc-Benchmarks-and-Specs.782932.0.html

Yes the memory is upgradeable although it's not clear if the laptop using regular ddr5 or sodimms

[allgamesonxeigpu]

Well I still don't know if the core ultra 5 125u uses shared memory. Techpowerup says it does. Notebookcheck says it doesn't. It may not matter though since all 32gb benchmarks on passmark seem to perform better with less memory. Got an awesome config ready with the e cores using process lasso. Can't wait to get my new laptop. The power constantly flickered during the storm but I was one of the lucky 50 percent in Houston that didn't lose power. It was quite a storm though. Sucks that the city won't be back to normal in time to get my birthday gift

Hello Allgamesonxeigpu,

Thank you for the quick response.

I will raise the case with our engineers to check if there is any other page or other important information that we can provide you regarding your concern.

Thank you so much for your patience and understanding.

thank you for your understanding. the information on notebookcheck may be erroneous. it looks like it stems from their knowledge that the arc chips run the same games that the dedicated graphics run so they incorrectly thought the chip didnt have shared memory. techpowerup seems to think that it does have shared memory so I don't know what to think. Ive been playing city skylines 2 at 15 fps on a core ultra 5 125u it was a lot of fun. not sure how beneficial a memory upgrade would be. anyway thank you for your reply.

Hello allgamesonxeigpu,

Thank you for the quick reply.

Let me share this document, refer user to 113 to 115, also page 208 of the datasheet that give some inside on how memory works for Ultra core processors.

If you still have clarifications, please let us know. Thank you.

what I gather from this is that even though the core ultra 5 125u is not called arc graphics. it is identical except instead of using up to 8 xe cores. it uses 4. there is also a lp4 u model which i don't have that uses 6400 lpddr5 memory instead of 5600 ddr5 memory.  that can be found on page 20. for whatever reason they don't explicitly say it but the core ultra 5 125u is just a core ultra 5 125h with some reduced features although it doesn't make this 100 percent clear. thank you.
