Intel flagship Arc GPU features 21.7 billion transistors, more than Navi 22 and GA104

Intel ACM-G10 GPU is bigger than NVIDIA’s GA104

Intel disclosed details on its new Arc GPU family, the ACM series based on Xe-HPG microarchitecture for gaming. 

The information about transistor count and die sizes of the ACM GPUs has not been disclosed to all media. However, it seems that HardwareUnboxed managed to obtain and confirm this information, which gives us an opportunity to compare the numbers with solutions from both Intel competitors.

According to their data, Intel ACM-G10 (previously referred to as DG2-512EU) is 406 mm² in size and has 21.7 billion transistors. Both values are bigger than AMD Navi 22 and NVIDIA GA104, supposedly the main competitors for this ARC GPU:

FP32 Performance based on the fastest known SKU13.5 TFLOPs

(RTX 3070 Ti)

The transistors’ density is higher than NVIDIA’s by 20% and 6% over AMD. All these GPUs use different process nodes though, from 8nm to 6nm.

Intel has only plans for two Alchemist GPUs: the ACM-G10 and ACM-G11. There were leaks of a potential 384EU variant called “G12”, however it seems that in the end the company decided that it is not needed and was not included in the mobile launch presentation.

The smaller Arc GPU has 157 mm² die and 7.2B transistors. This is more than AMD Navi 24 GPU (also fabricated using TSMC N6 process) with 107 mm² and 5.4B and NVIDIA GA107 (around 200 mm², but NVIDIA never confirmed the die size or transistor count for this GPU).

It was long-rumored that big Arc Alchemist GPU will compete with Radeon RX 6700 and GeForce RTX 3070 series and based on pure data alone, this seems to be plausible. Unfortunately, Intel has not provided any performance figures for its ACM-G10 processor yet. This part is set to launch with Arc 5 and Arc 7 mobile GPUs ‘early summer’, and desktop GPUs in ‘summer’.
