About the Intel Atom Z3740 CPU

The Intel Atom Z3740 is an end-of-life 4-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2013. It is part of Intel's Atom lineup, which is based on the Bay Trail-T microarchitecture. The Z3740 is compatible with Intel BGA 1380 motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the HD Graphics integrated graphics solution.

Memory and Cache

The Atom Z3740 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Atom Z3740 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 56 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1.

Cores and Clock Speeds

The Atom Z3740 features 4 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1333.0 MHz, and it can boost up to 1867.0 MHz 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 Atom Z3740 includes an integrated graphics solution called HD Graphics. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance

The Atom Z3740 has the 688th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.34% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i3-5015U CPU

The Intel Core i3-5015U is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q1 2015 with a suggested retail price of $275. It is part of Intel's Core i3 lineup, which is based on the Broadwell-U microarchitecture. The i3-5015U is compatible with Intel BGA 1168 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel HD 5500 integrated graphics solution.

Memory and Cache

The Core i3-5015U supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i3-5015U 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 3 MB.

Cores and Clock Speeds

The Core i3-5015U features 2 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.1 GHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i3-5015U includes an integrated graphics solution called Intel HD 5500. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance & Value

The Core i3-5015U has the 545th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 7.34% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 2,715 score and $275 launch price (MSRP) gives it a performance per dollar of 9.87. This is the 193rd best in value for the 3DMark 11 Perf. Physics benchmark.
