In terms of performance, the 6900HX is slightly faster than the Intel Core i7-12800H, but it is not significantly faster than the more energy-efficient 6900HS. While it is still a powerful processor for demanding apps and games, it does fall behind the 12th Gen Core i9 options.
A notable addition to this processor is the integrated GPU, the Radeon 680M, which is based on the RDNA2 architecture and offers 12 CUs (compute units) clocked at up to 2.4 GHz. This makes it the fastest integrated GPU at the time of its announcement.
One of the strengths of the Ryzen 9 6900HX is its power consumption, with a default TDP (thermal design power) of 45 W. This, combined with its 6 nm manufacturing process, makes for excellent energy efficiency.
In terms of technical specifications, the 6900HX has a clock rate of 3.3 GHz to 4.9 GHz, 512 KB of level 1 cache, 4 MB of level 2 cache, and 16 MB of level 3 cache. It is a 64-bit processor that supports x86 architecture and features such as XFR, FMA3, SSE 4.2, AVX2, and SMT. It has a maximum temperature of 95°C and is compatible with the FP7 socket.
The AMD Ryzen 9 6900HX was announced on January 4, 2022 and is now 368 days old. It is a powerful and energy-efficient processor that offers a range of new features and strong performance, making it a good choice for gaming laptops.
In addition to its strong performance and energy efficiency, the AMD Ryzen 9 6900HX also offers a range of new features that make it well-suited for gaming laptops.
One of these features is support for USB 4, which allows for transfer speeds of up to 40 Gbps. This makes it easy to connect high-speed devices such as external hard drives and graphics tablets to your laptop, allowing you to take advantage of their full capabilities.
The Ryzen 9 6900HX also supports PCI-E Gen 4, which allows for faster data transfer between the processor and other components in the system. This can be especially useful for gaming laptops, where fast data transfer is essential for smooth gameplay.
In terms of memory support, the 6900HX offers support for DDR5-4800MT/s or LPDDR5-6400MT/s. This allows for faster memory speeds and improved performance, especially in demanding apps and games.
Wireless connectivity is also improved with the inclusion of WiFi 6E and Bluetooth LE 5.2. WiFi 6E allows for faster and more stable wireless connections, while Bluetooth LE 5.2 allows for improved energy efficiency and faster data transfer.
Finally, the 6900HX offers support for DisplayPort 2 and AV1 decode. DisplayPort 2 allows for higher resolution and refresh rates, making it well-suited for gaming laptops with high-resolution displays. AV1 decode allows for improved video decoding, which can be beneficial for streaming video content or playing video games with high-quality graphics.
While the AMD Ryzen 9 6900HX is a strong performer in its own right, it is helpful to compare it to other processors to get a better understanding of its strengths and weaknesses.
One processor that is often compared to the 6900HX is the Intel Core i9-11900H. This is a processor designed for gaming laptops that is based on the 11th Gen Core architecture. It has 8 cores and 16 threads, and is clocked at speeds ranging from 2.5 GHz to 5.0 GHz. It also supports hyperthreading and is manufactured using the 10 nm process.
In terms of performance, the Core i9-11900H is generally considered to be slightly faster than the Ryzen 9 6900HX. This is especially true in single-threaded tasks, where the Core i9-11900H has a slight advantage due to its higher clock speeds. However, the Ryzen 9 6900HX tends to perform better in multi-threaded tasks due to its support for simultaneous multi-threading (SMT).
In terms of power consumption, the Core i9-11900H has a higher TDP of 35 W, which is lower than the 45 W TDP of the Ryzen 9 6900HX. This means that the Core i9-11900H may be more energy-efficient in certain situations.
Another processor that is often compared to the Ryzen 9 6900HX is the AMD Ryzen 9 5900HX. This is a processor based on the Cezanne generation of microarchitecture and is also designed for gaming laptops. It has 8 cores and 16 threads, and is clocked at speeds ranging from 3.3 GHz to 4.6 GHz. It also supports SMT and is manufactured using the 7 nm process.
In terms of performance, the Ryzen 9 5900HX is generally considered to be slightly slower than the Ryzen 9 6900HX. This is due to its lower clock speeds and older microarchitecture. However, it is still a strong performer and may be a good choice for those looking for a more affordable option.
In terms of power consumption, the Ryzen 9 5900HX has a similar TDP of 45 W, which is the same as the Ryzen 9 6900HX. This means that they have similar levels of energy efficiency.
Overall, the AMD Ryzen 9 6900HX is a strong performer that is well-suited for gaming laptops. While it may not be the fastest processor available, it offers a good balance of performance and energy efficiency, as well as a range of new features that make it well-suited for modern laptops.
