This 8-core, 16-thread processor offers impressive performance, power efficiency, and features that make it an attractive option for users who need a high-performance device for demanding tasks.
Architecture and Performance
The Ryzen 7 3700U is built on AMD’s Zen+ architecture, which provides significant improvements in IPC (instructions per clock) and power management. The processor features eight cores with four threads each, running at a base frequency of 2.3 GHz and a boost frequency of up to 4.0 GHz.
In terms of performance, the Ryzen 7 3700U delivers impressive results in various benchmarks. In Cinebench R15, it scored around 1,300 points in the multi-threaded test, outperforming Intel’s Core i7-1065G7 by a significant margin. Similarly, in Geekbench 5, it achieved scores of over 4,500 points in single-threaded and over 20,000 points in multi-threaded tests.
Power Efficiency
One of the key advantages of the Ryzen 7 3700U is its power efficiency. AMD has implemented various power-saving features, including Precision Boost Overdrive (PBO), which allows the processor to dynamically adjust its clock speed based on workload and thermal conditions. This results in improved battery life and reduced heat generation.
Integrated Graphics
The Ryzen 7 3700U integrates Radeon RX Vega 10 graphics, which provides a significant boost in graphics performance compared to Intel’s integrated UHD 630 graphics. In 3DMark Time Spy, the Vega 10 graphics achieved scores of over 1,500 points, outperforming Intel’s Core i7-1065G7 by around 30%.
Memory and Storage
The Ryzen 7 3700U supports up to 64GB of DDR4 memory at speeds of up to 3200 MHz. It also features four lanes of PCI Express 3.0 for storage devices, allowing for faster data transfer rates.
Thermal Design Power (TDP)
The Ryzen 7 3700U has a thermal design power (TDP) of 15W, making it suitable for thin and light laptops. This TDP is relatively low compared to Intel’s Core i7-1065G7, which has a TDP of 25W.
Comparison with Intel Core i7-1065G7
In comparison to the Intel Core i7-1065G7, the Ryzen 7 3700U offers:
- Higher core count (8 vs 4)
- Higher thread count (16 vs 8)
- Higher boost frequency (up to 4.0 GHz vs up to 3.9 GHz)
- Better power efficiency (15W TDP vs 25W TDP)
However, the Intel Core i7-1065G7 has a higher single-threaded performance due to its higher IPC and clock speed.
Conclusion
The AMD Ryzen 7 3700U is an impressive mobile processor that offers high-performance capabilities, power efficiency, and features that make it an attractive option for users who need a demanding device. Its ability to outperform Intel’s Core i7-1065G7 in multi-threaded workloads and its lower TDP make it a compelling choice for laptop manufacturers.
