According to AMD, the Pro 455 support DisplayPort 1.2 (altough 1.4 is supported by Polaris) and HDMI 2.0 (via USB-C adapter). See more details on the Polaris architecture here. The features of the Radeon Pro 455 are identical to the faster RX 460 and all other Polaris chips. The only option is to use modified drivers from. The optional Radeon Pro 460 offers 4 GB of VRAM, 1024 shaders and 1.86 TFLOPS and should be similar to the RX 460.Īpple and AMD don't provide driver updates for Windows using Bootcamp. A major drawback is the small VRAM size of only 2 GB GDDR5. The performance of the card could be similar to the Nvidia GeForce GTX 960M as the RX 460 is similar to the GTX 965M. The peak performance is rated at 1.3 TFLOPS and therefore 30% faster than the Pro 450, but clearly slower than the 1.86 TFLOPS of the Pro 460 and 2.2 TFLOPS of the RX460. Compared to the Radeon RX 460 (see for benchmarks), the Pro 455 features only 768 instead of 896 shaders and definately lower clock speeds. It is based on the small Polaris 11 chip which is manufactured in 14 nm FinFET at Globalfoundries. The Blackmagic eGPU Pro will cost $1,199 and it will be available in late November.The AMD Radeon Pro 455 is mobile graphics card for laptops that can be found in the high-end model of the Apple MacBook Pro Retina 15 Late 2016. The device will also provide 85W of power so users can charge MacBook Pros while connected. Included with the Blackmagic eGPU Pro are two Thunderbolt 3 ports, four USB 3 ports, an HDMI 2.0 port, and DisplayPort 1.4 port. It looks identical to the existing Blackmagic eGPU, which comes with a Radeon Pro 580 GPU for $699. The Blackmagic eGPU Pro will be equipped with a Radeon RX Vega 56 graphics processor and 8GB of HBM2 memory. This external GPU enclosure should dramatically increase overall performance and graphics power for Macs that have a Thunderbolt 3 port.
Apple also announced another GPU-boosting option for new Mac owners-the new Blackmagic eGPU Pro. Vega 56 and 64 graphics cards are already available in Apple's iMac Pro, a machine designed for creative professionals and power users. Offering Vega graphics cards (like the Vega 16 and 20 CPUs) in the MacBook Pros brings more consistency to the high-end Mac lineup, as well as the graphics power some users need to complete complex and creative projects.Īpple hasn't announced pricing for the new MacBook Pro models yet, but they will be available to order in November. Currently, the best GPU available in a MacBook Pro is the Radeon Pro 560X.
