AMD’s latest processor, the Ryzen Threadripper series has been marketed for gamers. One of its features is a game mode which was designed to give users more performance in gaming at the expense of peak hard CPU tasks.
AMD’s goal- described by us-is enables you to have a choice: having both an optimized machine that can do everything well or just enough power when needed without either limiting what it does best as most desktops tend to.
But this switch enables users to turn off half their processor if necessary allowing them flexibility depending upon whether they’re doing work-related projects besides playing games all day long.
We had originally thought that the effect was only present when running with simultaneous multi-threading (SMT) turned on. However, it appears as if one of two active dies within Threadripper is disabled in Game Mode – meaning your gameplay will be marginally smoother without SMT enabled or at least not impacted too much by this setting alone!
The developers were initially interpreting our tests incorrectly via an AMD slide deck they received before us; though after some back and forth between both parties we realized they may have been onto something all along since enabling GAME MODE seemed to be.

A Rose By Any Other Name
The original article on AnandTech incorrectly assumed that AMD was making Game mode available through both the BIOS and Ryzen Master software.
The misunderstanding resulted from a lack of communication between themselves, as well as what they had described at their pre-briefing for the SIGGRAPH conference in 2018 where it is stated that “Legacy Compatibility Mode uses half threads but still requires two cores” (Radeon Software Adrenalin 2019 Edition 20 Capacity Radeon RX 5700 XT Offering).
We regret this mistake has affected some users’ experience with our site; we’re sorry if you were expecting enhanced performance or smoother experiences based on these faulty assumptions made by ourselves before publishing content online today!
After we published our review, AMD reached out to us and informed us that the settings for disabling SMT were more complex than simply turning it off.
Instead of disabling a die entirely like we thought- which caused this error in the first place -they had told us adjusting some BIOSes can result in disabled Game Mode features rather than erasing all cores from your system (which would make 16C/32 T turn into 8).
To avoid any future problems with those kinds of misleading tests during reviews or anything else related to tech journalism; they offered access through Ryzen Master if ever needed again!
So What Is Game Mode?
For Ryzen Threadripper, AMD has defined two modes of operation depending on the use case. The first is Creator Mode which enables full cores and threads with maximum available bandwidth at a high price for latency in certain tests.
This default setting was benchmarked during our original review but we also looked into memory speeds as well to see how it performed compared against other platforms such as Intel Core i9-7900X Extreme Edition or even just one die from AMD’s recently launched $329 TRYTR4 16 core-hungry beast – ThreadRipper 1900x!
The advantages of a Unified Memory System (UMS) are that it allows for data to reside in either near or far memory, depending on where the application needs access.
The system does not discriminate between these two zones and therefore views all available DRAM slots as equal – resulting in improved performance when compared with Non-Uniform Memory Architectures(NUMA).
Benefits also arise because there is no need for any longer than one clock cycle latency before accessing their desired location within your operating system’s virtual address spaces; at DDR4-2400 rating speeds, this should take less than 20 nanoseconds!
For the 1950X in Game
For the 1950X in Game and Creator modes, we see that up until 8MB is reached where it probes near memory. Then at this point, main memory accesses become slower than average Ryzen while running on a central processing unit (CPU).
For those two modes specifically, you can expect an average wait time of around 20ns for accessing data from cores within your computer which should take much less time compared to what was seen before the L3 cache limit per CCX has been hit – 79 ns with Ryzens vs 108+/-20 [nS].
The other downside about using “Creator mode” appears when looking closely between these two types; 12% higher latencies measured among all sequences played out loud after measuring 8 MB into gameplay.
