AMD Navi 14 GPU Based Radeon Pro 5500M Spotted in Apple’s MacBook Pro With Full 24 CU Die, 8 GB GDDR6 Memory
AMD's Navi 14 based Radeon RX GPUs are launching soon but the SKUs we know are to based on a cut-down die which would feature up to 22 compute units. However, a full Navi 14 GPU based card has been spotted by ROGAME (via Videocardz) and is expected to be featured in Apple's latest Navi GPU powered MacBooks.
AMD Radeon Pro 5500M For Apple's MacBooks To Feature Full Navi 14 GPU With 1536 Cores, 8 GB GDDR6 VRAM
Update: AMD has officially announced both, the Radeon Pro 5500M and Radeon Pro 5300M mobile GPUs for Apple's 16" MacBook Pro. As expected, the AMD Radeon Pro 5500M comes with 24 CUs & 8 GB GDDR6 memory while the Radeon Pro 5300M features 20 CUs and 4 GB GDDR6 memory. The mobility GPUs are rated to feature up to 4.0 TFLOPs of FP32 performance and feature a TGP of 50 Watts.
“Today’s high-end creative professionals want the freedom to bring their ideas to life in the office or on the road without technology getting in their way,” said Scott Herkelman, corporate vice president and general manager, Radeon Technologies Group at AMD. “The Radeon™ Pro 5000M series GPUs provide MacBook Pro users with the horsepower and unmatched visual fidelity allowing them to focus on unleashing their creativity and delivering amazing results.”
We know that AMD is officially preparing three cards based on the Navi 14 die. These include the Radeon RX 5500 XT, the Radeon RX 5500 and the Radeon RX 5500M. Details for the first card are not revealed yet but it is expected to feature the full Navi 14 die too but it won't hit retail shelves soon. The Radeon RX 5500 and the Radeon RX 5500M on the other hand feature a cut-down Navi 14 GPU die with 1408 stream processors on each product.
The full Navi 14 GPU features 24 compute units or 1536 stream processors but we have seen no official marketing material that confirms a gaming product based on the full die. However, there has been a new chip spotted by ROGAME within the 16" Apple MacBook Pro. The MacBook showed up on both Geekbench 5 and 3DMark databases.
In 3DMark, the chip reportedly features a clock speed of 1431 MHz and a memory clock speed of 1472 MHz which points to a 12 Gbps pin speed. There's 8 GB of GDDR6 memory on the product that runs across a 128-bit bus interface. Configured alongside an Intel Core i9-9980H, the MacBook was able to score 2781 points. When talking about the breakdown of the score, we are looking at 7367 points for the CPU (Physics) and 2506 points for the GPU (Graphics). The clock frequency also doesn't match with any of the leaked IDs from a few weeks back.
One thing that might be happening is that AMD is supplying the full Navi 14 dies to Apple first for their new MacBook Pro 16" model which might explain the delay for the full Navi 14 graphics cards on the desktop front.
The graphics score is interesting and explains why there is so little information available around the 24 CU part and Navi 14 in general. Right off the bat, the graphics score is much lower than the GTX 1650 which scores around 3500 points. This means that drivers for Navi 14 GPUs or in this case, MacOS drivers aren't yet fully optimized. We have already seen the Radeon RX 5500 official benchmarks which show it to be much faster than the GTX 1650 and that's just the 22 CU part.
AMD Navi 14 Mobility GPU Lineup:
|GPU Name||GPU SKU||Compute Units||Stream Processors||Peak Clock||VRAM||Bandwidth||TGP|
|AMD Radeon Pro 5500M||Navi 14 XTX||24 CUs||1536||1300 MHz||8 GB GDDR6||192 GB/s||~75W|
|AMD Radeon RX 5500M||Navi 14 XTM||22 CUs||1408||1645 MHz||4 GB GDDR6||192 GB/s||50W|
|AMD Radeon Pro 5300M||Navi 14 XLM||20 CUs||1280||1230 MHz||4 GB GDDR6||192 GB/s||50W|
|AMD Radeon RX 5300M||Navi 14 XLM||22 CUs||1408||1445 MHz||3 GB GDDR6||168 GB/s||~50W|
Moving on to the Geekbench 5 OpenCL benchmark, a slightly different and higher-end MacBook Pro 16" configuration is put to the test. This one rocks an Intel Core i9-9980HK and here, the SKU has been clearly labeled as the Radeon Pro 5500M. This is to be expected since the MacBook being used is a professional variant. The benchmark reports 24 compute units or 1536 cores along with 8 GB of GDDR6 memory. The maximum frequency isn't reportedly correctly but the chip scores a total of 29230 points in the OpenCL benchmark. Once again, there's no optimization shown here since the comparative GTX 1650 results are above 35,000 points.
AMD hasn't provided a clear launch schedule for the Radeon RX 5500 series or Navi 14 GPU lineup, in general, making their mainstream/budget tier product launch very confusing. We will keep you posted once we have more information on the full Radeon RX Navi 14 configured graphics card for the desktop and mobility market.
