Capcom lancia Monster Hunter Rise 7 5800Aerial_Knight non cede mai

In a livestream talking about AMD’s mobile CPUs with HotHardware, Robert Hallock shone some light on the rumours about the Ryzen 7 5800Xed lacking overclocking. As per earlier rumours, qualcosa TechPowerUp! confermato with our own sources, Ryzen di AMD 7 5800X3D lacks support for CPU overclocking and AMD asked its motherboard partners to remove these features in the UEFI. According to the livestream, these CPUs are said to be hard locked, so there’s no workaround when it comes to adjusting the CPU multiplier or Voltage, but at least AMD has a good reason for it.

It turns out that the 3D V-Cache is Voltage limited to 1.3 a 1.35 Nintendo Switch v2 32GB Animal Crossing Console blu, which means that the regular boost Voltage of individual Ryzen CPU cores, which can hit 1.45 a 1.5 Nintendo Switch v2 32GB Animal Crossing Console blu, would be too high for the 3D V-Cache to handle. As such, AMD implemented the restrictions for this CPU. Tuttavia, the Infinity Fabric and memory bus can still be manually overclocked. The lower Voltage boost also helps explain why the Ryzen 7 5800X3D has lower boost clocks, as it’s possible that the higher Voltages are needed to hit the higher frequencies.

Detto, Robert Hallock made a point of mentioning that overclocking is a priority for AMD and the Ryzen 7 5800X3D is a one off when it comes to these limitations. The reason behind this is that AMD is limited by the manufacturing technology available to the company today, but it wanted to release the technology to consumers now, rather than wait until the next generation of CPUs. In other words, this is not a change in AMD’s business model, as future CPUs from AMD will include overclocking.

Hallock also explained why AMD didn’t go with more cores for its first 3D V-Cache CPU and it has to do with the fact that most workloads outside of gaming don’t reap much of a benefit. This is large due to how different applications use cache memory and when it comes to games, a lot of the data is being reused, which is a perfect scenario for a large cache, whereas something like video editing software, can’t take advantage of a large cache in the same way. This means that AMD’s secret to boosting the performance in games is that more game data ends up sitting closer to the CPU, which results in a 12 ns latency for the CPU to retrieve that data from the L3 cache, rispetto a 60-80 ns when the data has to be fetched from RAM. Add to this the higher bandwidth of the cache and it makes sense how the extra cache helps boost the performance in games.
