Intel Xe-HPG DG2 GPU, 128 EU, 1024 cores, clock at 2.2GHz

Intel seems to be testing a new variant of the DG2 GPU with Xe-HPG that clocks above 2GHz. This desktop discrete variant Geekbench database Tested on 11th generation desktop platforms.

The DG2 GPU with the Xe-HPG architecture has not only been tested on a desktop platform consisting of an Intel Core i5-11400T CPU and an ASUSB560M-PLUS motherboard with 16GB of DDR4-2133 memory, but is definitely a desktop discrete graphics card. .. However, there are some configurations not previously seen in the mobile Xe-LP variant.

Therefore, when the specification is reached, the Xe-HPG DG2 GPU rocks 128 execution units with a total of 1024 cores. The fastest Xe-LP GPU, Iris Xe Max rocks 96 EUs, delivering a total of 768 cores and clocks up to 1.65 GHz.last 128 EU Xe GPU Clock speed ratings were up to 1.90 GHz, but this time the same configuration is running at clocks up to 2.2 GHz, making it the first Intel GPU to break the 2.0 GHz barrier.

At the same time, the specs and clock speed look great, but the performance of the Intel Xe-HPG DG2 GPU isn’t very good, and it’s probably the bad driver to take responsibility here. The OpenCL score is 13,710, which is almost inconsistent with the AMD Radeon RX 550 graphics card. Therefore, when it comes to graphics performance, the last entry also shows performance, and Intel still needs a lot of tweaking when it comes to drivers for certain APIs and workloads. 1.9GHz variant Reached GeForce GTX 1650 Ti level performance. The lineup of Xe-HPG is Rumored to be released at CES2022 So they still left a lot of time for the job.

Here’s everything we know about the Intel Xe-HP GDG2 Gaming GPU lineup

Each Xe-HPG-based DG2 GPU SKU is available in a variety of configurations, from full fat chips to several cutdown variants. This is similar to NVIDIA’s Ampere GA102-400, GA102-200 naming convention, or AMD’s Navi 21 XTX, Navi 21 XT, Navi 21 XL naming convention.

Intel Xe-HPG DG2 512EU Discrete Gaming Graphics Card

The top DG2512 EU variant has only one configuration listed so far, with a full die with 4096 cores, a 256-bit bus interface, and up to 16 GB GDDR6 memory (8 GB GDDR6 is also listed). I will use it. Based on supply and yield, Intel has the potential to produce more variations of this flagship chip, but we can’t say for sure at this time.

The size of the DG512 EU chip is expected to be around 396mm2, which is larger than AMD RDNA2 and NVIDIA Ampere products. The DG2-512 GPU is available in a 37.5mm x 43mm BGA-2660 package. The size of NVIDIA’s Ampere GA104 is 392mm2. This means that the size of the Navi 22 GPU is 336mm2 or about 60mm2 smaller, while the size of the DG2 chip is comparable. This is not the final die size of the chip, but it should be very close.

NVIDIA has a tensor core and a much larger RT / FP32 core on the chip, and the AMD RDNA 2 chip has one ray accelerator unit for each CU and Infinity Cache. Intel is expected to equip the Xe-HPG GPU with hardware-accelerated ray tracing capabilities, and a recent tweet from Raja seems to point out hardware DL / ML capabilities that are useful for supersampling technology. ..

The Xe-HPG DG2 512 EU chip is recommended to have clocks up to 2.2 GHz, but I’m not sure if these are average clocks or maximum boost clocks. Also, Intel’s first TDP target was said to have been 225-250 W, but is now raised to around 275 W. If Intel wants to push the clock further, you can also expect a 300W variant with dual 8-pin connectors. I’ve already seen pictures of leaked PCBs and ES Xe-HP GDG2-based graphics cards. You can see it here..

Intel Xe-HPG DG2 384EU Discrete Gaming Graphics Card

Next is the Intel Xe-HPG DG2 384 GPU SKU. It is expected to consist of at least three variants. The full fat chip features 3072 cores, up to 12 GB of GDDR6 memory (6 GB of GDDR6 is also listed), and a 192 bit bus interface. Then there are two variants, 256EU and 192EU, consisting of 2048 cores and 1536 cores. Both variants have a 128-bit bus interface, but the 256 EUSKU comes with up to 8GB GDDR6 memory (also listed as 4GB GDDR6), and the 192EU variant has 4GB GDDR6 memory. Based on the specifications, these GPUs are positioned as mainstream components.

Videocardz Previously, it leaked the die configuration of the Intel Xe-HPG DG2 384 GPU variant that needed to measure 190mm2. The PCB Blueprint shows the location of the 192 bit bus interface and 6 memory modules to see the 6GB or 12GB GDDR6 memory capacity. The 384 and 256 EU SKUs are expected to have 16MB and 8MB smart caches, respectively. Clock speeds for 384 EU parts are reported at 600MHz base and 1800MHz turbo, while 256EU parts have 450MHz base and 1400MHz turbo clock.

Intel Xe-HPG DG2 128EU Discrete Gaming Graphics Card

And finally, there are Intel Xe-HPG DG2 128EU parts. The top-level configuration is a full fat SKU with 1024 cores, a 64-bit bus interface, and 4 GB GDDR6 memory. The cutdown variant comes with 96 EU or 768 cores and 4GB of GDDR6 memory working on a 64-bit bus interface. This GPU is very similar to the DG1 GPU-based discrete SDV board, but the DG2 has a better architectural design and definitely better performance than the first generation Xe GPU architecture. This lineup is sure to target the entry-level desktop discrete market based on specifications.
