About the AMD Ryzen 5 3450U CPU

The AMD Ryzen 5 3450U is a 4-core (8-thread) processor built for the mobile CPU market. The 3450U is compatible with FP5 motherboards and is fabricated on a 12 nm manufacturing process.

Memory and Cache

In terms of cache, the Ryzen 5 3450U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 384 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 4 MB.

Cores and Clock Speeds

The Ryzen 5 3450U features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2100.0 MHz, and it can boost up to 3500.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Ryzen 5 3450U does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance

The Ryzen 5 3450U has the 370th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 17.30% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i7-840QM CPU

The Intel Core i7-840QM is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q2 2010 with a suggested retail price of $568. It is part of Intel's Core i7 lineup, which is based on the Clarksfield microarchitecture. The i7-840QM is compatible with Intel Socket G1 motherboards and is fabricated on Intel's 45 nm manufacturing process.

Memory and Cache

The Core i7-840QM supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-840QM has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.

Cores and Clock Speeds

The Core i7-840QM features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1867.0 MHz, and it can boost up to 3.2 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i7-840QM does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Core i7-840QM has the 413th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 12.67% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 4,686 score and $568 launch price (MSRP) gives it a performance per dollar of 8.25. This is the 205th best in value for the 3DMark 11 Perf. Physics benchmark.
