Introduction

The Snapdragon 7s Gen 4 vs Snapdragon 7s Gen 3 vs Kirin 9000S comparison is useful because these chips take noticeably different approaches to mid-range and upper-mid-range smartphone performance.

The Snapdragon 7s Gen 4 was announced on August 19, 2025, and uses TSMC’s 4nm process. It has eight CPU cores based on Cortex-A720 and Cortex-A520 cores, together with an Adreno 810 GPU. NanoReview gives it a 44 overall score, with 41 for CPU, 18 for gaming and 91 for battery life.

The Snapdragon 7s Gen 3 was announced on August 20, 2024. It uses a very similar CPU layout and the same Adreno 810 GPU, but its prime CPU core is clocked lower. NanoReview scores it at 43 overall, also with a CPU score of 41 and battery score of 91.

The Kirin 9000S is older, announced on August 29, 2023, and manufactured by SMIC on a 7nm process. It uses an eight-core CPU built around TaiShan V120 and Cortex-A510 cores and a Maleoon 910 GPU. Its overall NanoReview score is 41, but its CPU score of 45 is actually higher than both Snapdragon competitors.

Quick Answer

The Snapdragon 7s Gen 4 is the overall winner in this NanoReview comparison with a score of 44, narrowly ahead of the Snapdragon 7s Gen 3 at 43 and Kirin 9000S at 41. The 7s Gen 4 improves CPU clock speed and graphics performance over its predecessor, while Kirin 9000S leads CPU scoring and AnTuTu but has much weaker gaming and battery ratings.

Specification Comparison

The specifications show that Snapdragon 7s Gen 4 is largely an evolution of the 7s Gen 3, while Kirin 9000S has stronger listed multimedia resolution and memory bandwidth despite its older manufacturing process.

CPU Architecture and Performance

Kirin 9000S has the highest NanoReview CPU score, but Snapdragon 7s Gen 4 has the strongest CPU specification within the two Snapdragon models.

Snapdragon 7s Gen 4 uses one Cortex-A720 core at 2.7GHz, three Cortex-A720 cores at 2.4GHz and four Cortex-A520 cores at 1.8GHz. Its 2.7GHz prime core is the main architectural change over the previous 7s Gen 3.

Snapdragon 7s Gen 3 uses the same 1+3+4 arrangement, but its prime Cortex-A720 reaches only 2.5GHz. The three performance cores and four efficiency cores retain the same 2.4GHz and 1.8GHz frequencies.

Kirin 9000S uses a different architecture: one TaiShan V120 core at 2.62GHz, three TaiShan V120 cores at 2.15GHz and four Cortex-A510 cores at 1.53GHz. It is built on 7nm and supports ARMv8-A.

NanoReview rates the Kirin 9000S at 45 CPU, compared with 41 for both Snapdragon 7s Gen 4 and 7s Gen 3. This is an important result because the overall winner is not automatically the CPU winner.

In Geekbench 6, Kirin 9000S records 1,325 single-core and 4,118 multi-core, compared with 1,223/3,168 for Snapdragon 7s Gen 4 and 1,161/3,390 for Snapdragon 7s Gen 3.

The practical interpretation is straightforward: Kirin 9000S is stronger in NanoReview’s current CPU measurements, while the 7s Gen 4’s higher prime-core frequency gives it a clear improvement over the 7s Gen 3 in single-core workloads.

GPU and Gaming

Snapdragon 7s Gen 4 is the gaming winner according to NanoReview, despite Kirin 9000S having the highest theoretical FLOPS figure.

The Snapdragon 7s Gen 4 and 7s Gen 3 both use an Adreno 810, but NanoReview lists different GPU frequencies. The 7s Gen 4 runs at 895MHz, while the 7s Gen 3 is listed at 1050MHz. Their theoretical FLOPS figures are therefore 458.2 and 537.6 GFLOPS, respectively.

Kirin 9000S uses Maleoon 910 at 750MHz and is listed at 1,536 GFLOPS, considerably higher than the two Snapdragon chips.

Yet the gaming scores tell a different story:

• Snapdragon 7s Gen 4: 18
• Snapdragon 7s Gen 3: 16
• Kirin 9000S: 12

NanoReview’s gaming score therefore favors Snapdragon 7s Gen 4.

This is a good example of why theoretical FLOPS should not be treated as a direct gaming ranking. Real gaming performance also depends on GPU architecture, drivers, graphics APIs, memory behavior and software optimization.

Manufacturing and Efficiency

Snapdragon 7s Gen 4 and Snapdragon 7s Gen 3 tie for efficiency with a NanoReview battery score of 91.

The two Snapdragon processors are manufactured by TSMC on a 4nm process, while Kirin 9000S uses a 7nm SMIC process.

NanoReview rates both Snapdragon chips at 91 for battery life, while Kirin 9000S receives 76. Therefore, the efficiency winner is a two-way tie between Snapdragon 7s Gen 4 and Snapdragon 7s Gen 3.

The equal battery rating is notable because the 7s Gen 4 has a higher prime-core clock than its predecessor. Its efficiency score has nevertheless remained unchanged in NanoReview’s current data.

Actual smartphone battery life still depends on display, battery capacity, modem usage, software and thermal behavior, so the NanoReview rating should be treated as a comparative indicator rather than a universal runtime guarantee.

RAM, Memory and Storage

Kirin 9000S has the highest listed memory bandwidth, while the two Snapdragon chips use newer and faster platform configurations in other areas.

Snapdragon 7s Gen 4 and 7s Gen 3 both use LPDDR5 at 3200MHz, with NanoReview listing 25.6Gb/s maximum bandwidth and up to 16GB RAM.

Kirin 9000S uses LPDDR5 at 2750MHz but has a wider 4×16-bit bus, resulting in 44Gb/s maximum bandwidth. It also supports up to 16GB RAM.

Storage presents another advantage for Kirin 9000S on paper. NanoReview lists UFS 3.1/UFS 4.0, while both Snapdragon chips support UFS 2.2/UFS 3.1.

For raw memory bandwidth and maximum listed storage standard, Kirin 9000S has the stronger specification.

AI and NPU

All three processors include dedicated AI hardware, but NanoReview does not provide directly comparable TOPS figures for them.

Snapdragon 7s Gen 4 and 7s Gen 3 are both listed with a dedicated NPU, while Kirin 9000S uses a Da Vinci NPU.

Because equivalent AI throughput figures are not provided for all three processors, a definitive AI winner cannot be established from NanoReview’s published specifications.

Real-world AI performance will also depend on supported models, framework optimization, precision and how applications divide workloads among the CPU, GPU and NPU.

Camera, ISP and Video

Kirin 9000S has the strongest listed video capability, while Snapdragon 7s Gen 4 and 7s Gen 3 support up to 200MP cameras.

NanoReview lists both Snapdragon 7s Gen 4 and 7s Gen 3 with support for a 200MP camera and 4K video at 30fps.

Kirin 9000S has no maximum camera-resolution figure listed on its NanoReview page, but it supports 4K video at 60fps, giving it a clear advantage in recording frame rate.

Kirin also supports a maximum display resolution of 3840×2160, compared with 2900×1300 on Snapdragon 7s Gen 4 and 1920×1200 on Snapdragon 7s Gen 3.

Camera quality itself cannot be determined from these maximum specifications alone. Sensor quality, ISP processing and device-level camera tuning remain important.

Display and Connectivity

Kirin 9000S has the strongest listed 5G speed and display-resolution specification, while Snapdragon 7s Gen 4 has the newest Bluetooth version.

NanoReview lists maximum 5G download speeds of 2.9Gbps for both Snapdragon 7s Gen 4 and Snapdragon 7s Gen 3, compared with 4.6Gbps for Kirin 9000S.

Wi-Fi is listed as Wi-Fi 6 on all three processors.

Bluetooth differs more clearly. Snapdragon 7s Gen 4 supports Bluetooth 6.0, Snapdragon 7s Gen 3 supports 5.4, and Kirin 9000S supports 5.2.

Therefore, Kirin wins on listed cellular throughput and maximum display resolution, while Snapdragon 7s Gen 4 wins on Bluetooth generation.

Benchmark Comparison

Kirin 9000S leads AnTuTu and Geekbench CPU testing, while Snapdragon 7s Gen 4 and 7s Gen 3 offer stronger gaming and efficiency ratings.

NanoReview’s current AnTuTu 11 results put Kirin 9000S first at 1,062,256, narrowly ahead of the two Snapdragon chips, which are essentially tied at 1,041,898 and 1,041,899.

Geekbench produces a stronger Kirin advantage in CPU testing, particularly multi-core performance. In contrast, GPU compute favors the Snapdragon processors by a large margin in NanoReview’s available Geekbench data.

This explains why the overall NanoReview ranking cannot be derived from one benchmark alone. The Snapdragon 7s Gen 4 combines competitive CPU performance with considerably stronger gaming and efficiency scores, producing the highest aggregate result.

Real-World Performance

Snapdragon 7s Gen 4 is the best-balanced option, Snapdragon 7s Gen 3 remains very close, and Kirin 9000S is strongest for CPU-heavy workloads and certain hardware specifications.

The 7s Gen 4 is particularly attractive for a modern mid-range phone. Its 4nm TSMC manufacturing, 2.7GHz prime core, Bluetooth 6.0 and improved gaming score make it a logical successor to the 7s Gen 3.

The 7s Gen 3 remains highly competitive because its CPU architecture is nearly identical. Its lower 2.5GHz prime clock limits single-core performance, but it actually records a higher Geekbench multi-core score than the 7s Gen 4 in NanoReview’s current figures.

Kirin 9000S is more complicated. Its CPU benchmark results are better than both Snapdragon chips, and its memory bandwidth, display capability, storage support and 5G specification are strong on paper. However, its 7nm process, low gaming score and 76 battery rating make it less balanced as an overall smartphone platform.
