IntelIntel Iris Plus Graphics 645 Mobile Specifications
GPU Core
Shader units and compute resources
The Intel Iris Plus Graphics 645 Mobile GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
Iris Plus Graphics 645 Mobile Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Iris Plus Graphics 645 Mobile's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The Iris Plus Graphics 645 Mobile by Intel dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
Intel's Iris Plus Graphics 645 Mobile Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Iris Plus Graphics 645 Mobile's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
Iris Plus Graphics 645 Mobile Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the Intel Iris Plus Graphics 645 Mobile against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.
Generation 9.5 Architecture & Process
Manufacturing and design details
The Intel Iris Plus Graphics 645 Mobile is built on Intel's Generation 9.5 architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the Iris Plus Graphics 645 Mobile will perform in GPU benchmarks compared to previous generations.
Power & Thermal
TDP and power requirements
Power specifications for the Intel Iris Plus Graphics 645 Mobile determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the Iris Plus Graphics 645 Mobile to maintain boost clocks without throttling.

About Intel Iris Plus Graphics 645 Mobile
The Intel Iris Plus Graphics 645 Mobile is a mobile integrated GPU built on the Coffee Lake GT3e chip, using Intel's Generation 9.5 architecture on a 14 nm+++ process. It was released on October 6, 2019, and is now end-of-life. The device is designed for portable devices, with display outputs dependent on the host system. It sits at the 50th percentile of all GPUs in the database, indicating a median position in the overall GPU population. The GPU has 384 shading units, 48 texture mapping units, and 6 ROPs, with a base clock of 300 MHz and a boost clock of 1050 MHz. These specifications define its compute capability, and the 15 W TDP places it in the low-power segment for integrated GPUs.
Power and Cooling
The TDP is 15 W, which places it in the low-power segment for integrated GPUs. This is a modest power envelope, typical for a mobile GPU that shares the host platform's thermal budget. The slot width is listed as IGP, meaning it is not a separate card and does not occupy a standard expansion slot. No power connectors are specified, and no suggested PSU is listed, which is consistent with an integrated GPU that draws power from the host platform rather than a dedicated power supply. The bus interface is Ring Bus, which ties the GPU to the system's internal fabric. Because it is an integrated GPU, the cooling is handled by the host system's existing thermal solution; the data does not specify a separate cooler requirement. The 15 W TDP means the GPU is power-constrained, and sustained performance will be limited by the thermal and power delivery of the host system. The base clock of 300 MHz and the boost clock of 1050 MHz indicate the operating range, but the actual clock will depend on the power headroom available in the host device. The lack of a dedicated PSU connector is a clear signal that this is a system-integrated part.
Ray Tracing and Feature Set
The chip has no RT cores and no tensor cores, as the data lists null values for both. This means there is no dedicated ray tracing hardware and no tensor-core acceleration for AI or machine learning workloads. The API support is modern, including DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The DirectX 12_1 feature level indicates support for certain features such as rasterizer-ordered views and conservative rasterization, but it does not include the DirectX Raytracing (DXR) tier that requires RT hardware. The FP16 rate is 1.613 TFLOPS with a 2:1 ratio to FP32, meaning the GPU can perform FP16 operations at twice the rate of FP32. This is useful for compute workloads that can utilize half-precision, but without tensor cores, there is no dedicated hardware for mixed-precision AI inference. The FP32 rate is 806.4 GFLOPS, which is the primary throughput for general-purpose graphics and compute tasks. The API support means the GPU is compatible with modern game engines and applications that use DirectX 12, OpenGL 4.6, or Vulkan 1.3, but the absence of RT cores means that ray-traced workloads will not be hardware-accelerated.
Benchmark Performance
The database shows an average benchmark score of 0, and the benchmark array is empty, so there are no direct scores to analyze. The GPU is at the 50th percentile of all GPUs in the database, which places it exactly at the median of the GPU population. This is a meaningful anchor: it means the GPU is neither above nor below the middle of the field. The raw compute rates provide context. The FP32 throughput is 806.4 GFLOPS, the texture rate is 50.40 GTexel/s, and the pixel rate is 6.300 GPixel/s. These are the maximum rates for these operations, derived from the 384 shading units, 48 TMUs, and 6 ROPs. The base clock of 300 MHz and the boost clock of 1050 MHz define the operating range, but the 15 W TDP means the GPU will likely not sustain the boost clock under sustained load. The 50th percentile ranking is consistent with a mid-tier integrated GPU, but the absence of specific benchmark scores means the data cannot quantify a specific performance delta against any named competitor. The FP16 rate of 1.613 TFLOPS with a 2:1 ratio suggests that FP16 workloads can be processed at twice the rate of FP32, which is relevant for certain compute tasks. The pixel rate of 6.
