Key Architectural Differences

AMD Ryzen 7 9700X features a traditional symmetric core design with 8 high-performance Zen 5 cores, each supporting simultaneous multithreading (SMT). This approach delivers consistent performance across all cores with a remarkably low 65W TDP, making it one of the most power-efficient processors in its class.

Intel Core Ultra 7 265KF adopts Intel’s hybrid architecture with 8 Performance cores (P-cores) and 12 Efficient cores (E-cores). The P-cores handle demanding single-threaded tasks, while E-cores manage background processes and lighter workloads. However, the KF variant lacks integrated graphics, requiring a discrete GPU.


Performance Analysis

Synthetic Benchmarks

Synthetic benchmarks provide a controlled environment to measure raw computational power. Here’s how both processors perform:

Benchmark AMD Ryzen 7 9700X Intel Core Ultra 7 265KF Winner
Cinebench R23 (Multi-Core) ~19,500 pts ~28,000 pts Intel (+44%)
Cinebench R23 (Single-Core) ~2,150 pts ~2,280 pts Intel (+6%)
Geekbench 6 Single-Core ~3,100 ~3,250 Intel
Geekbench 6 Multi-Core ~18,500 ~22,800 Intel

The Intel chip’s 20 cores (even with E-cores being less powerful) provide a significant advantage in heavily multi-threaded workloads. This makes it excellent for content creation, 3D rendering, and video encoding.

Productivity & Multi-Core Workloads

Workload AMD Ryzen 7 9700X Intel Core Ultra 7 265KF Winner
Video Encoding (HandBrake 4K H.265) ~48 FPS ~62 FPS Intel (+29%)
7-Zip Compression ~85,000 MIPS ~105,000 MIPS Intel (+24%)
Blender (BMW27 Render) ~3.2 min ~2.5 min Intel (22% faster)
Adobe Premiere Pro (4K Export) ~4.8 min ~4.1 min Intel (15% faster)

For 3D rendering and other heavily parallelized workloads, Intel’s core count advantage translates to real-world time savings.


Gaming Performance

Gaming is where things get interesting. While both processors are more than capable of driving high-end GPUs, there are some notable differences.

Gaming Benchmarks (1080p Ultra Settings with RTX 4080)

Game AMD Ryzen 7 9700X Intel Core Ultra 7 265KF Winner
Cyberpunk 2077 168 FPS 172 FPS Intel (+2%)
Red Dead Redemption 2 156 FPS 159 FPS Intel (+2%)
Starfield 142 FPS 138 FPS AMD (+3%)
CS2 (Counter-Strike 2) 612 FPS 645 FPS Intel (+5%)
Fortnite 385 FPS 398 FPS Intel (+3%)
Call of Duty: MW3 298 FPS 305 FPS Intel (+2%)
Baldur’s Gate 3 134 FPS 131 FPS AMD (+2%)
Hogwarts Legacy 118 FPS 121 FPS Intel (+3%)
Spider-Man Remastered 189 FPS 193 FPS Intel (+2%)
The Last of Us Part I 145 FPS 148 FPS Intel (+2%)

Average Gaming Performance:

  • AMD Ryzen 7 9700X: ~235 FPS
  • Intel Core Ultra 7 265KF: ~241 FPS
  • Winner: Intel Core Ultra 7 265KF (+2.5% average)

The gaming performance is remarkably close between these two processors. Intel holds a slight edge in most titles, particularly in competitive esports games like CS2. However, the difference is typically within 2–5% — barely noticeable in real-world gaming. At 1440p or 4K resolutions, the GPU becomes the bottleneck and performance differences essentially disappear.


Power Consumption & Efficiency

This is where AMD’s Ryzen 7 9700X truly shines:

Power Draw Comparison

Idle ~15W ~25W
Gaming (Average) ~55W ~110W
All-Core Load ~88W ~240W
Cinebench R23 ~85W ~235W

Winner: AMD Ryzen 7 9700X (significantly more efficient)

The Ryzen 7 9700X consumes roughly 40–60% less power than the Intel chip under load. This translates to:

  • Lower electricity bills over the processor’s lifetime
  • Less heat generation, requiring smaller/quieter cooling solutions
  • Better for small form factor (SFF) builds where thermal constraints matter
  • More environmentally friendly with reduced carbon footprint
