AMD Ryzen 9 7845HX vs AMD Ryzen 7 7745HX vs AMD Ryzen 9 7840HX

AMD Ryzen 9 7845HX

► remove from comparison AMD R9 7845HX

The AMD Ryzen 9 7845HX is a fast high-end laptop processor of the Dragon Range series. It offers 12 of the 16 cores based on the Zen 4 architecture that supports hyperthreading (24 threads). The cores clock from 3 (base) up to 5.2 GHz (single core boost). The 7845HX is the second-fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7900X.

The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.

Performance

The average 7845HX in our database is in the same league as the Core i9-13900HX, as far as multi-thread benchmark scores are concerned. This is a super-fast chip, as of mid 2023; of course, your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.

The R9 7845HX is rated at a TDP of 55 Watt and can be configured from 45 to 75 Watt (cTDP).

AMD Ryzen 7 7745HX

► remove from comparison AMD R7 7745HX

The AMD Ryzen 7 7745HX is a fast high-end laptop processor of the Dragon Range series. It offers 8 cores based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.6 (base) up to 5.1 GHz (single core boost).

The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, the 7745HX only uses one CCD) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.

Performance

The average 7745HX in our database is in the same league as the Core i5-13500HX and the Core i7-13705H, as far as multi-thread benchmark scores are concerned. This is a very fast chip, as of early 2023, and it will make both content creators and gamers happy - for the next two years or so, at least. Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

The R7 7745HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).

AMD Ryzen 9 7840HX

► remove from comparison AMD R9 7840HX

The AMD Ryzen 9 7840HX is a high-end notebook processorfrom the Dragon Range series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. The CPU uses the current Zen 4 architecture for the 12 cores and clocks these from 2.9 GHz (base clock) up to 5.1 GHz (single-core boost). The CPU offers 12 MB L2 cache and 64 MB L3 cache (i.e. a total of 76 MB cache). The 7840X consists of three chiplets, two CCD clusters with a maximum of 8 CPU cores in 5nm (71mm²) and one IO die in 6nm (122mm²) which are all manufactured at TSMC.

The performance of the Ryzen 9 should be significantly faster than the old Ryzen 9 6980HX (top model Rembrandt H, 8 cores, max 5 GHz). This is achieved by the additional cores, higher clock rate and improved architecture. Compared to the one year older Ryzen 9 7845HX, the 7840HX is clocked 100 MHz lower.

The chip also integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB 4), 28 PCIe 5.0 lanes (for GPUs and SSDs), a dual-channel DDR5-5200 memory controller and a small AMD Radeon 610M graphics card (2CUs, 400 - 2200 MHz).

The R9 7840HX is specified with 55 watts TDP and can be configured from 45 to 75 watts (cTDP).
