Radeon RX Vega 8 Mobile Graphics Cards – The Newest from AMD
AMD has recently released some new Radeon RX Vega Mobile graphics cards in the form of the Vega 8 and Vega 11 GPUs. These are impressive mobile devices, but they do come with trade-offs when compared to their desktop counterparts. In this article, we’ll discuss both new Vega graphics cards as well as their benefits and limitations based on AMD’s most recent public data. Let’s get started!
AMD’s Latest 3D VLIW4 Architecture
With a brand new architecture, Radeon RX Vega 8 graphics cards are ready to power your gaming laptop. Featuring a Radeon VLIW4 graphics processor and built on AMD’s newest 14nm process technology, there is no better way to play PC games, CAD software or high-end 3D models. You can do it all with ease while creating less noise and less heat! Not only that, but these latest chips offer a great mix of horsepower and efficiency that ensures smooth gameplay every time. If you’re ready for amazing mobile gaming and impressive performance in your work applications, then getting yourself one of these cards is a must! What’s more?
Increased Performance Across All Modern Gaming Titles
Gamers can expect up to 2.4x faster performance in games compared to older RadeonTM graphics cards in VR Ready configurations, with up to 82% more performance in Far Cry 5 and 63% more performance in HitmanTM when comparing RadeonTM RX Vega 56 mobile graphics cards vs RadeonTM R9 380 graphics cards. With RadeonTM FreeSync technology2, gamers can experience seamless, fluid movement throughout hi-res, heavy duty games. The AMD Free Performance display driver provides optimization for a wide variety of game titles for maximum performance benefits. Game developers are also taking advantage of DirectX® 12 and Vulkan® features alongside their new GPU architecture to bring out their most ambitious visions as well as improve quality across older titles.
Improved Performance in 3D Rendering Applications
Laptop graphics chips have become increasingly popular for use in high-end graphics rendering due to their portability and relatively cheap cost when compared to more powerful desktop models. Of course, mobile GPUs can’t quite match their desktop counterparts in terms of raw performance, but they’re getting closer all the time. Case in point: The new Radeon RX Vega 8 mobile GPU is pretty impressive stuff. It’s compatible with an assortment of notebooks designed to run on Intel’s Kaby Lake or Coffee Lake CPUs and comes packing a maximum clock speed of 1,250MHz with up to 4GB VRAM available. If you want one now—and have $1,000 (or less) handy—then here are a few places you can find them for sale online.
High-Bandwidth Cache Controller
One of the biggest new features in Vega is a redesigned high-bandwidth cache controller. High-bandwidth memory (HBM) is a revolutionary type of memory architecture that’s superfast, flexible, and power efficient. But HBM requires a different way of handling read and write operations; these have to be broken up into separate steps with data going through multiple layers of circuit boards before it reaches its final destination. That’s why AMD created its high-bandwidth cache controller. It breaks up reads and writes so they go straight to or come directly from system memory, thereby saving time—and reducing energy use while increasing performance at peak efficiency. In short, it makes HBM work fast—but also brings it down to earth in terms of power consumption.
Support for HDMI 2.0b & DisplayPort 1.4
First, AMD announced Rapid Packed Math support. This doubles throughput of FP16 operations and lets Vega crunch 4x as many 16-bit ops as before. Next, they added a new Shader Cache, which is essentially a fast L2 cache that can store info about previously used shaders and get them loaded into L1 quickly for reuse. This helps drastically cut down on repeated shader recompiles, which has been an issue for desktop GPU users in recent times. On mobile chips (at least in laptops), it could help make using software that supports OpenCL much faster by accelerating compute-intensive tasks—plus not slowing things down if you’re using programs that don’t use OpenCL at all.
64 Next-Gen Compute Units
Both cards feature 64 next-gen compute units (NCUs) and both cards possess a total of 4,096 stream processors. This is no less than 64% more stream processors and NCUs than previous generation high-end mobile GPU options (the Radeon R9 M295X had 2816 SPs). In addition to that, it looks like AMD is using a brand new architecture compared to what’s on their current mobile GPUs (r7 M370X / r7 M270X / r5 M255 / r5 M330). Both boards are based on AMD’s GCN 5.0 architecture which includes a lot of new features such as asynchronous shaders, faster clockspeeds, improved tessellation performance, improved triangle/packing efficiency and more.
Rapid Packed Math & Shader Expansions
Once upon a time, an instruction-packed 16-lane PCIe slot was considered overkill for most graphics cards. Today, that’s changed. Both Nvidia and AMD have been utilizing them for some time, particularly for high-end consumer cards as well as professional applications that benefit from GPU compute and/or simultaneous multi-projection (SMP). Even with double or quad CrossFire/SLI setups being common these days, there can be value in having lots of lanes available to maximize performance and minimize bottlenecks.
