New benchmark leaks for Intel’s Xe3 architecture–based Panther Lake integrated graphics suggest a dramatic leap in iGPU performance. Recent engineering sample results show the Intel Arc B390 scoring over 7,000 points in the 3DMark Time Spy Graphics test—placing it well ahead of today’s mainstream iGPUs and approaching the performance levels of entry-level discrete GPUs for the first time.
According to data shared by reliable leaker @OneRaichu, the Arc B390’s Time Spy Graphics score (~7,000) is roughly double the Radeon 890M, AMD’s RDNA 3.5-based iGPU. Earlier leaks had already suggested performance close to the GeForce RTX 3050 Ti Mobile, but the latest score even surpasses the desktop RTX 3050 (≈6,323 points). If confirmed, the 12-core Xe3 GPU in Panther Lake would become Intel’s most powerful integrated graphics solution to date.
However, synthetic results like Time Spy tend to favor certain GPU architectures, and Intel GPUs historically perform well in such benchmarks. Real-world gaming performance may not show the same proportional uplift. Even so, the score reflects a major generational gain—nearly 2× higher than Arrow Lake-H’s Arc 140T, rising from ~3,720 to ~7,000 points.
Time Spy Graphics Score Comparison #
| Model | Time Spy Graphics Score |
|---|---|
| Radeon 8060S | 10,924 |
| Radeon 8050S | 9,278 |
| Intel Arc B390 | 7,000 |
| GeForce RTX 3050 | 6,323 |
| Intel Arc 140T | 3,720 |
| Radeon 890M | 3,374 |
While the Arc B390 does not yet reach AMD’s high-TDP Strix Halo-class Radeon 8050S/8060S, those GPUs operate in a different power and market tier. Within its intended segment, Intel’s B390 looks extremely competitive.
Beyond Time Spy, @OneRaichu also reported that the Arc B390 achieves roughly 6,000 points in the Steel Nomad Light test—about 90% higher than the Radeon 890M and 80% above the Arc 140T. These stress-heavy workloads further highlight improvements in Xe3 execution units, cache, and texture throughput.
Implications for Laptops and Handheld Devices #
With growing demand for high-performance handheld consoles, thin-and-light laptops, and efficient portable platforms, integrated GPU performance is becoming a decisive factor. Panther Lake’s near-RTX-3050 performance could allow:
- Higher-quality graphics on handheld gaming devices
- Better frame rates in thin-and-light laptops without discrete GPUs
- Lower overall platform cost compared to dedicated GPU solutions
If Intel manages competitive pricing, the Arc B390 may be more attractive than high-end Strix Halo–based platforms for mass-market devices.
Final Outlook #
All current data is based on engineering samples and unverified leaks, and final performance may shift as production silicon, firmware, and drivers mature. Key real-world metrics—gaming performance, power efficiency, thermal behavior, frequency scaling, and memory bandwidth handling—will only be confirmed once Panther Lake officially launches.
Still, evidence continues to build: Intel’s Xe3 architecture represents a significant step forward for integrated graphics, setting a new performance baseline for future mobile devices and compact gaming hardware.
