The AMD Ryzen 9 8945HX and Intel Arc B370 pairing produces one of the most lopsided combinations in the database: a 95th-percentile CPU joined to a 5th-percentile GPU. The CPU's average benchmark score of 76,212 places it alongside desktop and server flagships, while the GPU's 3DMark Steel Nomad DX12 score of 1,184 puts it in the company of parts from over a decade ago. The combined percentile of 50 reflects a system that is mid-tier overall but extreme in both directions. No measured FPS rows exist for this exact combination — the FACT PACK contains no measuredFps data — so all frame-rate discussion below is estimated from the benchmark scores.

Upgrade Path and Platform

The Ryzen 9 8945HX uses AMD Socket FL1, a mobile socket, which anchors this platform to laptop form factors. The CPU is built on Zen 4 architecture in the Dragon Range codename, fabricated on a 5nm TSMC process with 13,140 million transistors across two 71 mm² dies. Memory support is DDR5 with a dual-channel interface and a maximum bandwidth of 83.2 GB/s. That memory bandwidth is shared with the GPU, which uses System Shared memory — the GPU's size, type, and bus width are all System Shared, and bandwidth is System Dependent. The platform provides PCIe Gen 5 with 28 lanes (CPU only), which is a high-bandwidth connection for NVMe storage and peripheral devices. However, the Arc B370 is an integrated graphics processor — its bus interface is IGP and its slot width is IGP — so those PCIe lanes are not occupied by a discrete graphics card.

Power requirements are modest. The CPU has a TDP of 55W and the GPU has a TDP of 25W. The GPU has no power connectors and no suggested PSU rating, meaning it draws all power through the motherboard. This is a light power envelope for a laptop. The CPU's multiplier is unlocked, so overclocking is theoretically possible, though the 55W TDP limits practical headroom in a laptop chassis. A sensible next upgrade for this platform is adding more DDR5 system memory — since the GPU uses System Shared memory, increasing memory capacity directly benefits both the CPU and GPU. For users who need more graphics power, the 28 PCIe Gen 5 lanes could support a discrete GPU in a chassis that accommodates it, but the mobile socket and laptop build class restrict that path.

GPU Analysis

The Intel Arc B370 is an integrated graphics processor based on Xe3-LPG architecture, built on a 3nm Intel process. It has 1,280 shading units, 40 texture mapping units, 20 render output units, and 10 ray-tracing cores. Clocks are a 300 MHz base and a 2400 MHz boost. Pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s. Compute throughput is 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 at a 2:1 ratio. The GPU's memory configuration is entirely System Shared — no dedicated VRAM — and bandwidth is System Dependent, which means it uses the CPU's 83.2 GB/s DDR5 memory path.

The only benchmark score for this GPU is the 3DMark Steel Nomad DX12 result of 1,184, placing it at the 5th percentile of all GPUs. The nearest rivals are all older parts: the ATI Mobility Radeon HD 5570 scores 1,186 (0.2% above the B370), the ATI Radeon HD 5770 scores 1,190 (0.5% above), the AMD Radeon HD 7650M scores 1,192 (0.7% above), and the AMD FirePro M2000 scores 1,168 (1.4% below). The data shows the Arc B370 is statistically indistinguishable from entry-level GPUs from a decade earlier — the deltaPct range spans just -0.7% to +1.4%.

The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it has modern API coverage. But the raw throughput is low. The 10 ray-tracing cores offer ray tracing support, but with 6.144 TFLOPS FP32 and a 5th-percentile score, ray-traced workloads will be extremely slow. The 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate are hard limits for fill-rate-heavy workloads. This GPU is a basic display and office GPU, not a rendering or gaming part.

Benchmark Performance

The CPU benchmarks are strong across every test. Cinebench R23 shows 42,713 multi-core and 6,030 single-core. Cinebench R20 shows 17,939 multi-core and 2,532 single-core. Cinebench R15 shows 4,305 multi-core and 607 single-core. PassMark results include 51,405 multi-thread, 3,907 single-thread, 195,180 integer math, 117,453 floating point math, 677,755 data compression, 40,836 data encryption, 49,823 extended instructions, 78,781 random string sorting, and 2,168 physics.

The average CPU score of 76,212 places the Ryzen 9 8945HX at the 95th percentile of all CPUs. The nearest rivals are: Intel Core Ultra 9 285HX at 76,155 (0.1% lower), AMD EPYC Embedded 8224P at 76,492 (0.4% higher), AMD Ryzen Threadripper PRO 9945WX at 76,513 (0.4% higher), and AMD Ryzen 9 9950X3D at 75,779 (0.6% lower). The data shows the 8945HX is effectively the same speed as the Core Ultra 9 285HX and sits within a fraction of a percent of desktop and server flagship processors.

The GPU's 3DMark Steel Nomad score of 1,184 is at the 5th percentile. Combined with the CPU's 95th percentile, the system's overall percentile of 50 reflects a wide gap. As noted, there is no measured FPS data for this combination; all FPS discussion is estimated from the scores. The CPU will not be the bottleneck in any graphics workload — the GPU will.

Who Should Build It

This build targets users who need maximum CPU compute performance in a laptop and who can accept minimal graphics capability. The 16-core, 32-thread Ryzen 9 8945HX, at the 95th percentile, is an excellent engine for software development, data analysis, and multi-threaded productivity. The Cinebench R23 multi-core score of 42,713 demonstrates strong CPU rendering and encoding capability. The GPU at the 5th percentile makes this unsuitable for gaming at any resolution — the 1,184 Steel Nomad score is within 0.7% of the AMD Radeon HD 7650M, an entry-level part from the early 2010s.

Content creators who work with CPU-heavy workflows — video encoding, 3D scene processing, or large compilations — will benefit. Students running simulations, scientific code, or large build jobs will find the 32 threads valuable. Developers who compile code, run test suites, and handle container workloads will see strong performance from the 195,180 integer math score. Small business workstations running office suites, database queries, and web services will have more CPU power than needed. Anyone who expects gaming or GPU-accelerated machine learning from this build will be disappointed.

Usage Scenarios

High-refresh gaming: Not viable. The GPU's 5th-percentile score of 1,184 Steel Nomad will produce low frame rates in any modern game. The CPU's power is irrelevant when the GPU caps the frame rate.

Video editing: The 42,713 Cinebench R23 multi-core score accelerates export and timeline operations. The GPU's 6.144 TFLOPS FP32 is weak for GPU-accelerated effects, so effects-heavy work will be slow.

3D rendering: CPU-based rendering will be excellent — the 17,939 Cinebench R20 multi-core score indicates strong performance for rendering engines that use the CPU. GPU-based rendering will be limited by the B370's low throughput and shared memory.

Software development: Compilation and multi-threaded builds run fast with 32 threads. The 3,907 single-thread score keeps interactive development responsive, and the 195,180 integer math score accelerates code execution.

Student and office work: The CPU's 3,907 single-thread score handles documents, spreadsheets, and web applications smoothly. The 55W CPU TDP and 25W GPU TDP make this an efficient laptop for campus use.

Streaming: The 32 threads can handle software encoding, but the GPU cannot produce playable frame rates in most games, so gameplay streaming will be poor.

Balance and Bottleneck

The GPU is the bottleneck in any graphics workload. The CPU sits at the 95th percentile and the GPU at the 5th — a 90-point gap. The GPU's 1,184 Steel Nomad score and 6.144 TFLOPS FP32 cap any frame rate the CPU could otherwise drive. In CPU-only workloads, the system is well balanced. In gaming, the GPU is the limiting component, and it is not close.

The shared memory is a second bottleneck. The GPU uses System Shared DDR5 memory, so it competes with the CPU for the same 83.2 GB/s bandwidth. The CPU's 64 MB L3 cache mitigates this for CPU-bound workloads, but the GPU has no separate cache. The GPU's 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate are additional hard limits. The CPU is never the bottleneck — the 42,713 Cinebench R23 multi-core score is far more than the GPU can consume.

Build Overview

This is a laptop-class build (buildClass "laptop") pairing the AMD Ryzen 9 8945HX with the Intel Arc B370. The combined percentile is 50, placing the system at the midpoint of all builds. But the CPU and GPU percentiles are at opposite extremes: 95th and 5th. This is a CPU-first mobile workstation, not a gaming laptop. The CPU provides top-tier compute performance, and the GPU provides only basic display output and light graphics acceleration.

CPU Analysis

It was released on 2025-04-22 and is in active production.

The benchmark data shows this CPU is at the top of the mobile processor market. The average score of 76,212 places it at the 95th percentile of all CPUs. It is 0.1% above the Intel Core Ultra 9 285HX, 0.4% below both the AMD EPYC Embedded 8224P and the AMD Ryzen Threadripper PRO 9945WX, and 0.6% above the AMD Ryzen 9 9950X3D. The Cinebench R23 multi-core score of 42,713 is a strong multi-threaded result, and the single-core score of 6,030 is strong for single-threaded applications. The 195,180 integer math and 117,453 floating point math PassMark results indicate heavy compute capability.

For real workloads, the 16 cores and 32 threads accelerate CPU rendering, video encoding, compilation, and scientific computing. The 64 MB L3 cache keeps data close for CPU-bound tasks. The 83.2 GB/s memory bandwidth is sufficient for the CPU, though it is shared with the GPU. The unlocked multiplier gives overclocking headroom in theory, but the 55W TDP in a laptop chassis limits practical gains. This CPU is a strong choice for compute-heavy mobile workloads.
