Apple’s new Apple TV 4K doubles RAM but apps stay capped at 2 gigabytes

This is a new development in a story we reported earlier: Apple confirms October 13 'Welcome Home' event in New York City.

Reports dated Nov. 15, 2026 described the Apple TV 4K (4th generation) with an A19 processor, 128 gigabytes of storage, and 8 gigabytes of RAM, but tvOS still caps each app and game at 2 gigabytes of memory, leaving the additional RAM unavailable to individual applications.

Apple set the new Apple TV 4K price at $299, a figure reports connect in part to memory chip supply constraints.

In June 2026, Apple increased U.S. prices for the current model. The current model starts at $199 for the 64 gigabyte Wi-Fi version or $249 for the 128 gigabyte Wi-Fi-plus-Ethernet version. Earlier Apple TV models carried a $129 price tag, and an Apple TV and HomePod minis once cost roughly $327 combined, while $299 now purchases only the streaming box.

The new Apple TV 4K runs under a tvOS limit that holds each app and game to 2 gigabytes of RAM, matching the cap on the prior model. Once an app allocates more than 2 gigabytes of memory, the system force-quits it. An Apple developer API called os_proc_available_memory reports 2 gigabytes to an app, and the API gives the same figure on the Apple TV 4K (3rd generation). Individual applications cannot use the additional memory under the current tvOS software, and whether Apple maintained the limit as policy or by oversight remains unclear.

Tests published on Nov. 10, 2026 found that the A19 chip runs the CPU 50 percent faster than the A15 in the earlier Apple TV, and the same tests found graphics performance twice as high. Apple uses the A19 in the iPhone 17 as well, and the 2022 model pairs an A15 Bionic processor with 4 gigabytes of RAM. Apple designed the faster chip to support Siri AI.

Games built for heavy graphics easily reach the 2 gigabyte RAM ceiling on the new Apple TV 4K. Apple sells the device as a gaming platform for supported controllers, and console-style titles most likely reach the limit.

AI helps the game decomp community run AAA studio games on devices such as the Apple TV, and earlier projects in that community reached the 2 gigabyte tvOS limit and had hoped the new model would ease that pressure.

TVPort is a Mac application that turns Nintendo Switch games copied from a user’s console into software for Apple TV. tvOS shuts down TVPort apps at 2,097 megabytes, compared with roughly 3.2 gigabytes of memory available to a game on a Nintendo Switch. The tool sidesteps the limit by storing game memory in a file that tvOS pages out to flash storage, and the A19 chip does not remove the need for that workaround.

Streaming clients make up most Apple TV apps, and their modest memory needs mean viewers watching shows will not notice the limit. tvOS sets an app bundle ceiling at roughly 4 gigabytes, while allowing apps to set aside about 20 gigabytes for certain assets. Developers can list as much as 20 gigabytes of additional content on the App Store through On-Demand Resources, and tvOS 27 removes On-Demand Resources, pointing developers to Background Assets in its place.

Siri AI is available on the Apple TV 4K (2nd generation) and newer models, and the third-generation model runs Siri AI on 4 gigabytes of RAM. Some observers have speculated that Apple sets aside part of the system memory to help Siri AI run, while demanding Siri AI requests on Apple TV shift to a linked iPhone or a server backend. Reports say tvOS 27 plans to bring a Siri app to Apple TV, but the extent of its AI features remains unknown.

Gadget Review reported that Apple went nearly four years without shipping a hardware update for the Apple TV 4K before the new model. Its September reporting pointed to an A17 Pro processor or something newer for the device, and a MacRumors report dated Sept. 8 pointed to evidence of an A19-generation chip. Apple confirmed neither the A17 Pro nor the A19 before launch, and Apple had not confirmed the final memory size before launch.

Gadget Review also reported that an Apple image asset that leaked showed an unreleased device labeled Apple TV 4K (4th generation), and the leak suggested an internal performance refresh rather than a visible redesign, with no release date set. Reports had expected the memory to rise to roughly 8 gigabytes from the current model’s 4 gigabytes. October has long served as a common window for Apple announcements.

Rival devices from Amazon, Roku, and others cost less, but their software falls short of tvOS. Apple’s press release promised “greater responsiveness, faster navigation, and smoother animations.”
