Intel Atom Z3736G vs Intel Atom Z3785 vs Intel Atom Z3680

Intel Atom Z3736G

► remove from comparison Intel Z3736G

The Intel Atom Z3736G is a power-efficient quad-core SoC for tablets (Android or Windows). It is clocked at 1.33 - 2.16 GHz and part of the Bay Trail-T platform. Thanks to the specially optimized 22nm low-power design process (P1271) with Tri-Gate transistors, performance and energy efficiency have been significantly improved compared to its predecessor. In contrast to the Z3736F, the Z3736G only offers a 32 bit single-channel DDR3L-RS-1333 memory controller (max. 1 GB, 5.3 GB/s).

Architecture

The processor cores are based on the new Silvermont architecture, which is an out-of-order design for the first time. The increased utilization of the pipeline and many other improvements (optimized branch prediction, increased buffers, and enhanced decoders) have increased the performance per clock by about 50 percent. At the same time, however, the Hyper-Threading feature of the previous generation has been removed. Other major additions are the support for new instruction set extensions such as SSE 4.1 and 4.2 as well as AES-NI (depending on the model).

Performance

Thanks to 4 CPU cores and the improved performance per clock, the Z3736G is significantly faster than previous Intel Atoms like the Z2760. Depending on the benchmark, the Z3736G competes with AMDs Kabini APU A4-5000. For everyday tasks such as Internet or Office the performance is adequate, but not for very complex Windows software or modern games. Compared to ARM SoCs for Android systems, the Z3736G is placed in the upper mid-range segment.

Graphics

The HD Graphics (Bay Trail) is based on the Intel Gen7 architecture, which supports DirectX 11 and is also found in the Ivy Bridge series (e.g. HD Graphics 4000). With only 4 EUs (Execution Units) and a relatively low clock speed of up to 646 MHz, the GPU is even slower than the HD Graphics (Ivy Bridge). Therefore, only older and less demanding games (like simple Android titles) will run fluently. However, video acceleration and other multimedia applications are no problem for the chip.

Power Consumption

The entire SoC is rated at an SDP of 2.2 W, which indicates a TDP of less than 4 W. Thus, the chip can be used in passively cooled tablets.

Intel Atom Z3785

► remove from comparison Intel Z3785

The Intel Atom Z3785 is a power efficient quad-core SoC for Windows and Android tablets. It is clocked at 1.49 - 2.41 GHz and part of the Bay Trail-T platform. Thanks to the specially optimized 22 nanometer low-power process (P1271) with tri-gate transistors, performance and energy efficiency have been significantly improved compared to its predecessor.

Compared to the Z3775, the Z3785 offers slightly increased clock rates for the CPU, GPU and memory controller.

Architecture

The processor cores are based on the new Silvermont architecture, which is an out-of-order design for the first time. The increased utilization of the pipeline and many other improvements (optimized branch prediction, increased buffers, enhanced decoders) have increased the performance per clock by about 50 percent. At the same time, however, the Hyper-Threading feature of the previous generation has been removed. Other major changes are the support for new instruction set extensions such as SSE 4.1 and 4.2 as well as AES-NI (depending on the model).

Performance

Thanks to 4 CPU cores and a clock speed of 1.49 - 2.41 GHz, the Z3785 is significantly faster than previous Intel Atoms, e.g. the Z2760. The Z3785 even beats some of the Kabini APUs like the AMD A4-5000, as well as ARM SoCs like Tegra 4 and the Snapdragon 800. For everyday tasks such as Internet or Office the performance is adequate, but not for very complex (Windows) software or modern games.

Graphics

The HD Graphics (Bay Trail) is based on the Intel Gen7 architecture, which supports DirectX 11 and is also found in the Ivy Bridge series (e.g. HD Graphics 4000). With only 4 EUs (Execution Units) and a relatively low clock speed of up to 833 MHz, the GPU is even slower than the HD Graphics (Ivy Bridge) and comparable to the Qualcomm Adreno 320 (as found in the Snapdragon 600). Therefore, only older and less demanding Windows games will run fluently. However, video acceleration and display resolutions up to 2560 x 1600 pixels are no problem for the chip.

Power Consumption

The entire SoC is rated at an SDP of 2.2 watts, which indicates a TDP of less than 4 watts. Thus, the chip can be used in passively cooled tablets.

Intel Atom Z3680

► remove from comparison Intel Z3680

The Intel Atom Z3680 is a power efficient dual-core SoC for Windows and Android tablets. It is clocked at 1.33 - 2.0 GHz and part of the Bay Trail-T platform. Thanks to the specially optimized 22 nanometer low-power process (P1271) with tri-gate transistors, performance and energy efficiency have been significantly improved compared to its predecessor.

Architecture

The processor cores are based on the new Silvermont architecture, which is an out-of-order design for the first time. The increased utilization of the pipeline and many other improvements (optimized branch prediction, increased buffers, enhanced decoders) have increased the performance per clock by about 50 percent. At the same time, however, the Hyper-Threading feature of the previous generation has been removed. Other major changes are the support for new instruction set extensions such as SSE 4.1 and 4.2 as well as AES-NI (depending on the model).

Performance

Thanks to the improved performance per clock, the Z3680 is faster than previous Intel Atoms, e.g. the Z2760. Presumably, the Z3680 even competes with AMD APUs like the AMD A4-4355M. For simple everyday tasks such as Internet or Office the performance is adequate, but not for complex software or modern games.

Graphics

The HD Graphics (Bay Trail) is based on the Intel Gen7 architecture, which supports DirectX 11 and is also found in the Ivy Bridge series (e.g. HD Graphics 4000). With only 4 EUs (Execution Units) and a relatively low clock speed of up to 667 MHz, the GPU is even slower than the HD Graphics (Ivy Bridge). Therefore, only older and less demanding Windows games will run fluently. However, video acceleration and display resolutions up to 1280 x 800 pixels are no problem for the chip.

Power Consumption

The entire SoC should be rated at an SDP of about 2 watts, which would indicate a TDP of less than 4 watts. Thus, the chip can be used in passively cooled tablets.
