News Imagination reveals new power-efficient DXTP GPU for laptops and mobile devices

[Admin]

Imagination's new GPU IP, DXTP, promises to bring its best yet AI GPU capabilities to low-power consumer devices.

Both the DXTP-48-1536 and DXTP-48-1536 are clocked at 1 GHz.

Both this sentence and the preceding table duplicate the same model number, whereas I think the second model should be DXTP-64-2048.

Performance-wise, the latter seems roughly on par with the GTX 1050 Ti, which has already been surpassed by iGPUs from AMD and Intel.

Here's a detailed feature list, from the spec page:

Headline features

• Dual-Rate FP16
• OpenCL Compute Libraries
• Fragment Shading Rate
• 2D Dual-Rate Texturing
• Pipelined Data Masters
• RISC-V Firmware
• ASTC HDR Support
• HyperLane Virtualisation

​

Interestingly, I don't see any mention of ray tracing. Given the level of detail it goes into (e.g. texture compression, HDR, etc.), I take that to imply RT support is lacking.

Both flavors of DXTP are RISC-V-based chips

I didn't see anything clearly stating that. I think the "RISC-V Firmware" feature is simply referring to support for RISC-V based host processors.

Windows on RISC-V is a distant pipe dream.

They go on to mention how other members of the same product family do have Windows support:

"DXTP is the final product of Imagination’s D-Series GPU family which includes the high-performance IMG DXD with DirectX FL11_0 for the desktop market"
​

So, I think the author is on the wrong track. And just because these can be used by RISC-V CPUs doesn't mean they're only supported on RISC-V.

In a statement, Peter Richardson of Counterpoint Research says, "The global smartphone market is experiencing a resurgence, propelled by cutting-edge AI features such as personal agents and enhanced photography."

The AI performance of this IP seems years behind the market!

"the Samsung Galaxy S24 series, with its Snapdragon 8 Gen 3 chipset, has a more powerful NPU at 70 TOPS, compared to the 45 TOPS in the Google Pixel 9 Pro's Tensor G4 chipset."

While the IP has already been licensed for smartphone and automotive uses, Imagination hopes the GPU will be used in desktop and laptop deployments.

Well, their specs page does list that among the "use cases", but I almost wonder if that was a copy-paste error, because their DXD (which came first) is their IP aimed at the desktop market. Furthermore, their press release says nothing about DXTP being targeted at desktops. It clearly wouldn't be viable, there. Even for laptops, it's a bit of a stretch.

I think you forget that Moorethread is using their IP to build desktop GPUs

Imagination IP? Yes. Not this IP, though. Most likely, cards like their S80 utilize Imagination's B-series IP:

IMG B-Series GPU - Imagination

IMG B-Series is a range of GPU IP that takes all the advances of IMG A-Series, the fastest GPU IP ever created, and adds even more performance.

Here's an article confirming it's what Innosilicon used for products of that same vintage:

​

In future dGPUs, Moore Threads would most likely be using the DXD IP, which was announced last November:

Imagination launches brand new line of high-performance GPU IP with DirectX  - Imagination

IMG DXD is a scalable GPU IP tailor-made for desktop, laptop and cloud gaming graphics experiences.

They still havent released complete open source drivers for the "old" gpu...
Incomplete or nothing for some model...
