The Benefits of Simultaneous Multi-Threading (SMT) in AMD Processors
Simultaneous Multi-Threading (SMT) has been a significant development in AMD processors, particularly with the introduction of the first-generation Ryzen processors. SMT enables two Threads to run simultaneously on a single processor core, effectively doubling the number of logical processes that an operating system can handle. With the advancement of AMD's Ryzen CPUs, mainstream core counts have skyrocketed, with the Ryzen 3000 and 5000 series now offering 16 cores and 32 threads for mainstream parts. This begs the question: how does SMT benefit gaming performance, and does it come at the cost of overall performance?
The Impact on Gaming Performance
When SMT was initially introduced with the first-generation Ryzen processors, there were some performance issues in certain games. Windows, at the time, was not optimized to handle the increased core and thread count, resulting in detrimental performance in specific gaming scenarios. However, through extensive testing and collaboration between AMD, Microsoft, and game developers, patches and updates were released to address and resolve these issues.
In 2021, gaming performance with SMT enabled has significantly improved. To better understand the impact, we conducted tests using the Ryzen 9 5950X paired with an MSI B550 motherboard and a Radeon RX 6800 XT graphics card. We compared three core count configurations: 16 cores and 32 threads (with SMT enabled), 16 cores and 16 threads (with SMT disabled), and 8 cores and 16 threads (achievable by disabling a single CCD). Additionally, we tested with two different clock frequencies: a fixed multiplier of 4200MHz and Precision Boost Overdrive (PBO) enabled.
Testing Methodology
To assess the benefits and drawbacks of SMT in gaming, we employed a mixture of gaming and creative professional workloads in our testing methodology. By doing so, we aimed to provide a comprehensive overview of how SMT impacts both aspects.
In our testing, we utilized various benchmarking tools and applications, such as Blender, Fry Bench, Corona 1.3, Handbrake, and Adobe Premiere, to evaluate performance across different scenarios. We also conducted gaming tests on titles like Rise of the Tomb Raider, Batman: Arkham Knight, Far Cry New DAWN, Borderlands 3, Assassin's Creed Valhalla, Horizon Zero Dawn, CS:GO, and Call of Duty.
Results: Creative Professional Applications
In professional applications like Blender and Fry Bench, which heavily utilize multiple threads and cores, the performance benefits of SMT were evident. With SMT enabled, the Ryzen 9 5950X demonstrated significantly faster rendering times and higher ray generation rates compared to configurations with SMT disabled or fewer cores and threads. The results showcased the impressive scaling capabilities of the Ryzen architecture.
Results: Gaming Performance
When it comes to gaming, the Ryzen 9 5950X may not be the ideal CPU solely focused on gaming due to the abundance of cores and threads. However, we conducted tests to assess the impact of SMT on gaming performance in 2021. Our gaming benchmarks revealed that while there were no significant performance gains from enabling SMT, there was also no noticeable performance degradation. The Ryzen 9 5950X performed admirably across a range of titles, showcasing the balance between gaming and multi-threaded performance.
Conclusions
In conclusion, the benefits of SMT in AMD processors are predominantly observed in professional applications, with significant speed-ups seen in tasks like rendering and ray generation. On the gaming front, while SMT does not offer substantial performance improvements, it also does not negatively impact gaming performance. For the majority of users and applications, there is no need to disable SMT. However, some legacy applications may not be optimized for SMT on AMD processors.
Pros and Cons of SMT
Pros:
- Significant performance improvements in professional applications
- No noticeable gaming performance degradation
- Efficient utilization of multiple threads and cores
Cons:
- Legacy applications may not be optimized for SMT
- Excessive core/thread count may not be fully utilized in gaming scenarios
FAQ
Q: Can disabling SMT improve gaming performance?
A: Disabling SMT may have a marginal impact on gaming performance in some cases, but it is generally not recommended for most users as the benefits of SMT outweigh the drawbacks.
Q: Does SMT affect all games in the same way?
A: SMT's impact on gaming performance may vary depending on the Game and its level of optimization for multi-threading. However, in general, the difference is minimal and not significant enough to warrant disabling SMT.
Q: Are there any downsides to enabling SMT?
A: Enabling SMT can result in increased power consumption and potentially higher operating temperatures. However, these downsides are generally outweighed by the performance benefits in multi-threaded workloads.
Q: Is SMT exclusive to AMD processors?
A: No, SMT is not exclusive to AMD processors. Intel has its own version of SMT called Hyper-Threading.
Q: Should I prioritize high core counts or high clock speeds for gaming?
A: In gaming, it is generally more important to prioritize higher clock speeds over higher core counts. However, the ideal balance between the two will depend on individual game requirements and overall system configuration.
Q: Can SMT improve performance in other multi-threaded tasks?
A: Yes, SMT can significantly improve performance in tasks that make use of multiple threads, such as video editing, rendering, and encoding.
