Apple's Mac Lineups to See Significant Graphics Upgrades as New GPU Launches Loom

Major graphics processing providers AMD and Nvidia are set to unveil new GPU products this year featuring Global Foundries' 14 nm FinFET and TSMC's 16 nm FinFET Plus processor nodes, respectively, allowing for significant improvements in graphics performance.

AMD's "Polaris" and Nvidia's "Pascal" architectures both utilize the latest FinFET silicon processes and will represent the first GPU process node change since 28 nm GPUs debuted in 2011. Both AMD and Nvidia skipped the intermediate 20 nm node, elongating the typical release cycle of consumer graphics processors.


While TSMC had traditionally provided multiple process offerings within a node, including one specifically tailored to higher power applications such as GPUs, the company found that the traditional planar geometries of its 20 nm node gave the firm less differentiation with its normal set of tweaks, rendering it a poor candidate for power hungry GPUs.

In a statement released earlier this year, AMD claimed that the new 14 nm Polaris GPUs will offer over double the performance per watt of their 28 nm predecessors. This news also confirmed AMD's use of Global Foundries' 14 nm FinFET process, rather than TSMC's 16 nm process, which Nvidia will use. While AMD confirmed the use of TSMC for its higher power product offerings, any products developed from that process node would be destined for the Mac Pro only, as Apple has traditionally used mobile GPUs for its notebook and iMac product lines.

The new FinFET process nodes promise a big performance jump for AMD's Polaris architecture

Product launches for these new GPUs are expected to occur around the summer timeframe. While Nvidia introduced its massive new Tesla P100 graphics card just this week, one rumor pegs the broader launch of the company's GeForce Pascal line around the time of Computex, which takes place from May 31 to June 4.

In addition to the new process nodes, both new architectures are expected to utilize a variety of new high-speed memories such as GDDR5x and HBM2, which promise improved memory bandwidth and memory size, in HBM2's case. AMD has already previously successfully launched a product utilizing a new 3DIC memory technology with their debut of the "Fury" line in 2015.

Though GPU rumor cycles tend to focus on desktop products, AMD's CEO stated that both desktops and laptops featuring the new Polaris GPUs are expected to launch before the back to school season. Apple has traditionally alternated between GPU offerings from both AMD and Nvidia when it comes to its product lines, with AMD owning the wins for the latest iterations of both the 27-inch iMac and MacBook Pro lines.

The MacBook Pro in particular is due for an update, and rumors have suggested new models could arrive at WWDC in June, but it is unclear whether Apple would be able to feature the upcoming GPUs within that timeframe. Apple has sometimes been very quick to incorporate the latest technology from its partners, but other times as waited quite some time before upgrading. Updates for the 27-inch iMac are less imminent, as the line was just upgraded to Intel's latest Skylake processors in October.

How often do people upgrade their Macs?
I haven't since 2011 and 2014 (besides upping the RAM in the iMac)...

Should I be upgrading? :p

I'm still using my 2011 iMac at home. Nice machine with the integrated DVD player. Every five years is about my desktop upgrade cycle. I'm going to hold off until end of year to see if I can get these better GPUs.

Doesn't matter for me as long as Apple stubbornly won't be putting those into at least one version of a 13" MacBook Pro.
These GPUs are not even destined for the 15" MBP...This article is referring to desktop GPUs (only suitable for something like an iMac or Mac Pro). But I would not disagree that having a dedicated GPU in my 13" MBP wouldn't be sweet...At least HDMI 2.0 please!

It looks like this article is just summarizing what is already known for months and has no evidence that any of these desktop GPUs will show up in new Macs this year. iMac will not use these GPUs, they need the mobile GPUs, which the 16nm versions are rumored to start mass production for later this year or early next year.

Unless Apple has signed an agreement to grab early access to these GPUs, it is extremely unlikely Apple will put any of these 16nm GPUs in most of their desktop Macs this year.

Apple hasn't been able to get early access to any new CPU/GPU for years now, I don't see this changing this year.

Only the Mac Pro may benefit this year from 16nm server GPUs but these GPUs are very expensive right out of the gate, so I don't see it happening this year.

It's up to Apple if they want to add discrete GPUs back to Macbook Pro. The Polaris 10 is destined for both low power to workstation lines.

They should update the GPU's just to shut Palmer Lucky up.
It's palmer Luckey...Have some respect for the guy, at least spell his name right...He is pioneering a new technology that is allowing us to see things like we never have before...The euphoria I get when putting on a VR headset was similar to the first time I ever used one of Apple's touchscreens

Do I you use the DVD player?
