Rockchip RK3288 vs Qualcomm Snapdragon 800 MSM8974 vs Qualcomm Snapdragon 801 APQ8074AB
Rockchip RK3288
► remove from comparisonThe Rockchip RK3288 is a mid-range ARM SoC for Android and Chrome OS mobile systems. It integrates four Cortex-A12 cores clocked at up to 1.8 GHz. ARM calls these cores Cortex-A17 due to them having very similar performance levels. The SoC includes an ARM Mali-T760 MP4 (also called Mali-T764) GPU clocked at 600 MHz and a dual-channel DDR3, DDR3L, LPDDR2, LPDDR3 memory controller.
The ARM Cortex-A12 is the successor to the Cortex-A9 and is based on a 32 Bit ARMv7-A microarchitecture. A single A12 core should be roughly 40 % more powerful than an A9 core according to ARM.
The integrated video engine supports encoding of H.264, VP8, and MVC videos up to 1080p. Decoding is supported for videos up to 4K H.264 and 10 Bit H.265.
The chip is manufactured under a 28 nm HKMG process.
Qualcomm Snapdragon 800 MSM8974
► remove from comparisonThe Qualcomm Snapdragon 800 MSM8974 is an ARM-based SoC for tablets and smartphones. It is built at TSMC in a 28nm HPM (High Performance Mobile) HKMG process, whereas the Snapdragon 600 was manufactured in 28nm LP. In addition to 4 CPU cores with a clock speed of up to 2.3 GHz, the chip also integrates an Adreno 330 GPU up to 450 MHz, an LPDDR3-1600 memory controller and various radio modules (UMTS/LTE, WiFi, Bluetooth, GPS).
Processor
The CPU portion is based on Qualcomm's Krait architecture, which is compatible with ARMv7 ISA. Compared to the Snapdragon 600 (Krait 300), the new Krait 400 cores of the Snapdragon 800 have been tweaked just slightly with faster L2 cache. Thanks to a clock rate of up to 2.3 GHz and a high performance per MHz somewhere between an ARM Cortex-A9 and a Cortex-A15, the Snapdragon 800 offers very strong CPU performance. The S800 competes with the Nvidia Tegra 4, Samsung Exynos 5420 and Apple A7 and is therefore one of the fastest ARM SoCs on the market as of 2013.
Graphics
Another difference between the Snapdragon 600 and 800 is the graphics unit. While the S600 implements an Adreno 320 (400 to 450 MHz), the S800 features the faster Adreno 330 (450 MHz). Both GPUs offer the same amount of texture units (8 TMUs), but the Adreno 330 has 50 percent more shaders (probably 6x SIMD16 vs. 4x SIMD16 of the previous generation). In conjunction with the higher memory bandwidth, the performance is significantly better. As a result, the Adreno 330 is slightly faster than the Mali-T628 (Exynos 5420) and the PowerVR G6430 (Apple A7). Depending on the device and cooling, however, the performance may vary. The GPU supports OpenGL ES 3.0 as well as OpenCL 1.2.
Features
Furthermore, the MSM8974 supports many wireless technologies: Bluetooth 4.0, WLAN, IEEE 802.11a/b/g/n/ac (2.4/5 GHz), GSM (GPRS, EDGE), W-CDMA/UMTS (HSDPA, HSUPA, HSPA+, cat.29 DC-HSPA+), MBMS, cat.4 LTE, CDMA2000 (1X RTT, 1 × EV-DO Rel.0/Rev.A/Rev.B, 1× EV-DO Rev.A MC, 1× Adv Rev.A/Rev.B) and TD-SCDMA.
The MSM8974 can encode and play UHD 4K videos in 3840x2160 at 30 FPS (120 Mbps H.264 High Profile) sumiltaneously via dedicated hardware. Moreover, it supports both USB 2.0 and 3.0 and cameras up to 55 megapixels and stereoscopic 3D.
Power Consumption
Thanks to the new 28nm HPM HKMG process, the energy efficiency has been improved significantly compared to its LP 28nm S600 predecessor. Depending on the field of application, the maximum power consumption should be about 3 W for smartphones or 4 W or greater for tablets. This should be similar to comparable ARM SoCs currently in the market.
Qualcomm Snapdragon 801 APQ8074AB
► remove from comparisonThe Qualcomm Snapdragon 801 APQ8074AB is an ARM-based SoC for (mainly android) tablets. It is built at TSMC in a 28nm HPM (High Performance Mobile) HKMG process and includes 4 Krait 400 cores at up to 2.45 GHz and a Adreno 330 at up to 578 MHz. Furthermore, the SoC integrates a LPDDR3-1866 memory controller as well as WLAN 802.11ac, Bluetooth 4.0 and GPS (but no cellular modem). Compared to the Snapdragon 800 chips like the MSM8974AB, the 801 offers a higher clock rate for GPU and CPU and support for eMMC 5.0.
Processor
The CPU portion is based on Qualcomm's Krait architecture, which is compatible with the ARMv7 ISA. Compared to the Snapdragon 600 (Krait 300), the new Krait 400 cores of the Snapdragon 801 have been tweaked just slightly with faster L2 cache. Thanks to a clock rate of up to 2.36 GHz and a high performance per MHz somewhere between an ARM Cortex-A9 and a Cortex-A15, the Snapdragon 801 offers very strong CPU performance. The S801 competes with the Nvidia Tegra 4, Samsung Exynos 5420 and Apple A7 and is therefore one of the fastest ARM SoCs on the market in the beginning of 2014 (till the Snapdragon 805 arrives).
Graphics
Another difference between the Snapdragon 600 and 800/801 is the graphics unit. While the S600 implements an Adreno 320 (400 to 450 MHz), the S800 and S801 features the faster Adreno 330 (APQ8074AB: 578 MHz). Both GPUs offer the same amount of texture units (8 TMUs), but the Adreno 330 has 50 percent more shaders (probably 6x SIMD16 vs. 4x SIMD16 of the previous generation). In conjunction with the higher memory bandwidth, the performance is significantly better. As a result, the Adreno 330 is slightly faster than the Mali-T628 (Exynos 5420) and comparable to the PowerVR G6430 (Apple A7). Depending on the device and cooling, however, the performance may vary. The GPU supports OpenGL ES 3.0 as well as OpenCL 1.2.
Features
Furthermore, the MSM8974AC supports the wireless technologies Bluetooth 4.0 as well as WLAN (IEEE 802.11a/b/g/n/ac 2.4/5 GHz). However, the APQ8074AB does not offer an integrated cellular modem.
The Snapdragon 801 can encode and play UHD 4K videos in 3840x2160 at 30 FPS (120 Mbps H.264 High Profile) simultaneously via dedicated hardware. Moreover, it supports both USB 2.0 and 3.0 and cameras up to 55 megapixels and stereoscopic 3D.
Power Consumption
Thanks to the new 28nm HPM HKMG process, the energy efficiency has been improved significantly compared to its LP 28nm S600 predecessor. Depending on the field of application, the maximum power consumption should be about 4 W. This should be similar to comparable ARM SoCs currently in the market. However, the APQ8074AB will likely need a little more power than the slightly lower clocked MSM8974.
