Radeon HD 8730A 

Released April, 2013
  • 650 MHz
  • 1 GB DDR3

The A8-4500M takes a pretty major chunk out of the GPU (one third of the GPU cores are gone along with a slight drop in maximum clock speed) while maintaining roughly 80% of the CPU performance, so it can fit into slightly cheaper laptops but will likely drop gaming performance from “moderate” to “light.

But, with some precise system setup, we think we have found at least one example where the output on the screen in the viewport (companion monitor) can, in fact, match the experience of the HMD.

NVIDIA Announces a Fallout 4 Mod

It is designed to show off GameWorks technologies, such as volumetric lighting and HBAO+, more heavily than Bethesda did with the base game.
If you're wondering why NVIDIA has a game development studio, they are mostly responsible for bringing content from the PC to their Shield devices, such as Half-Life 2 and Portal.
Though the Radeon RX 480 was released last month, based on AMD's latest Polaris, we are bringing in our first board partner.
Ed Crisler, NA PR/Marketing Manager for Sapphire will be joining us in studio to talk about the RX 480 and Sapphire's plans for custom cards.
On the prototype Radeon Pro SSG the M.2 slots are actually able to be seen as drives by the system and OS so it is essentially acting as if there was a PCI-E adapter card in a slot on the motherboard holding those drives but that may not be the case should this product actually hit the market.
Several commentors mentioned using a PCI-E based SSD in a second slot on the motherboard accessed much like GPUs in CrossFire communicate now (DMA over the PCI-E bus) which is an interesting idea that I had not considered.
Alongside the launch of new Radeon Pro WX (workstation) series graphics cards, AMD teased an interesting new Radeon Pro product: the Radeon Pro SSG.
With the Radeon Pro SSG, this idea is not fully realized (it is more of a sidestep), but it will move performance further.
