AMD Radeon HD 8450G IGP

The AMD Radeon HD 8450G IGP is an integrated graphics processor built on the TeraScale 3 architecture, fabricated by GlobalFoundries on a 32 nm process node. The chip, codenamed Scrapper, integrates 1,303 million transistors on a 246 mm² die, yielding a transistor density of 5.3M per square millimeter. It belongs to the Richland Mobile generation of TeraScale 3 IGPs and carries a 35 W TDP, with a slot width of IGP and a bus interface of IGP confirming its fully integrated nature. Released on May 22, 2013, the part is now listed as end-of-life, with the TeraScale 2 IGP as its predecessor and the GCN 2.0 IGP as its successor.

Benchmark Performance

The Radeon HD 8450G IGP operates with a base clock of 533 MHz and a boost clock of 720 MHz. The device delivers 276.5 GFLOPS of FP32 compute throughput from its 192 shading units. The pixel fill rate is 2.880 GPixel/s, produced by 4 ROPs, while the texture fill rate is 8.640 GTexel/s, produced by 12 texture mapping units. These figures define the raw execution capacity of the silicon, independent of any system-level bottlenecks.

The benchmark database places this GPU at the 50th percentile among all GPUs tracked. This median position indicates that the HD 8450G sits exactly at the midpoint of the performance distribution, outperforming half of all GPUs in the database while trailing the other half. Its average benchmark score is 0, reflecting the absence of standardized benchmark submissions for this integrated part rather than a literal zero-performance result.

The compute characteristics reveal a design oriented toward texture throughput rather than pixel output. The 12 TMUs deliver 8.640 GTexel/s of texture fill, while the 4 ROPs produce 2.880 GPixel/s of pixel fill. This allocation is typical for an integrated GPU, where texture sampling workloads are more common than heavy pixel shading. For a 35 W integrated solution, the 276.5 GFLOPS figure positions it as a modest performer, adequate for basic rendering workloads and older game titles.

The boost clock of 720 MHz represents a substantial increase over the base clock of 533 MHz, providing additional performance headroom when thermal and power conditions permit. This dynamic clocking behavior is a common trait in mobile-oriented parts, where power budgets fluctuate with system load. The gap between base and boost clocks suggests that the GPU can sustain higher performance in short bursts but will settle at the lower clock under sustained load. The 192 shading units, 12 TMUs, and 4 ROPs define a fixed execution pipeline that cannot be upgraded or modified; this is a fixed-function configuration determined by the silicon design.

How It Compares

The nearestRivals data for this product is empty, meaning no direct competitor comparisons with specific scores or delta percentages are available in the database. However, the product's lineage provides context for its positioning. It succeeds the TeraScale 2 IGP and is succeeded by the GCN 2.0 IGP. This places the HD 8450G in the transition period between two distinct graphics architectures, representing the mature refinement of the TeraScale design before AMD's pivot to Graphics Core Next.

The 50th percentile ranking is notable for an integrated part from the 2013 era. Many IGPs from that period fall below the median, so the HD 8450G's median position suggests it was a capable integrated solution relative to the broader GPU landscape at the time of its release. The percentile figure of 50 places it exactly at the midpoint of all GPUs tracked in the database, a respectable position for a part with no dedicated memory and a shared power budget.

Within the Richland Mobile generation, the HD 8450G occupies a specific tier defined by its 192 shading units, 12 TMUs, and 4 ROPs. These execution resources, combined with the 35 W TDP, define a power-conscious design intended for portable devices. The 32 nm process node from GlobalFoundries, with 1,303 million transistors on a 246 mm² die, represents the manufacturing technology of its era. The transistor density of 5.3M per square millimeter reflects the design rules of that process generation.

Memory Subsystem

The Radeon HD 8450G IGP uses System Shared memory for all graphics operations. The memory size, type, and bus width are all marked as System Shared, meaning the GPU has no dedicated VRAM of its own and instead borrows from the host system's main memory. The bandwidth is listed as System Dependent, indicating that performance scales with the host platform's memory configuration. The System Shared memory type means that there is no dedicated graphics memory allocation, and the system firmware determines how much memory is reserved for graphics operations.

This architectural choice has significant implications for high-resolution workloads. With no dedicated frame buffer, the GPU must compete with the CPU for memory bandwidth. The effective bandwidth available to the graphics engine depends entirely on the system's memory channels and clock speeds. A single-channel configuration would reduce available bandwidth compared to dual-channel, directly impacting fill-rate-limited scenarios.

The pixel rate of 2.880 GPixel/s and texture rate of 8.640 GTexel/s are theoretical maximums that assume sufficient memory bandwidth. In practice, the System Dependent bandwidth may become a bottleneck, particularly at higher resolutions where frame buffer traffic increases. For an integrated part, this is a common trade-off: reduced power consumption in exchange for lower memory performance compared to discrete solutions with dedicated VRAM.

The combination of 4 ROPs and shared memory bandwidth will likely limit performance at higher resolutions. The 2.880 GPixel/s pixel rate is sufficient for modest resolutions but will struggle with heavy overdraw or large render targets. The System Dependent nature of the bandwidth means that users with faster system memory will see better graphics performance, while those with slower memory will experience more pronounced bottlenecks.

FAQ

Ray Tracing and Feature Set

The Radeon HD 8450G IGP has no ray tracing cores and no tensor cores. The TeraScale 3 architecture predates both hardware ray tracing and AI-accelerated tensor operations, placing the device firmly in the rasterization-only era of graphics processing. The absence of RT and tensor cores means that any ray tracing or AI workloads would need to be handled through compute shaders on the 192 shading units, which would be inefficient given the 276.5 GFLOPS FP32 throughput.

The API support includes DirectX 11.2 (11_0) and OpenGL 4.4. Vulkan is not supported, which means modern Vulkan-based titles and engines that rely on Vulkan for low-overhead rendering will not run on this hardware. The lack of Vulkan support is particularly significant because it rules out modern cross-platform game engines that default to Vulkan on non-Windows platforms. The DirectX 11.2 support, while adequate for its era, limits the GPU to older or less demanding titles.

The display outputs are listed as Portable Device Dependent, meaning the available connectors and output capabilities depend entirely on the laptop or portable device in which the IGP is integrated. This is typical for integrated graphics, where the system board determines the physical display interfaces.

The 12 TMUs and 4 ROPs define the texture and pixel processing capacity. The texture rate of 8.640 GTexel/s allows for reasonable texture sampling in older games, while the 4 ROPs cap pixel throughput at 2.880 GPixel/s. For the era, this was a modest but functional configuration for entry-level mobile gaming and general desktop use.

The transistor count of 1,303 million on a 246 mm² die with a density of 5.3M per square millimeter reflects the 32 nm manufacturing technology. The feature set as a whole — no RT cores, no tensor cores, no Vulkan — defines a GPU that is firmly anchored to its 2013 release context, with capabilities that match the DirectX 11.2 and OpenGL 4.4 API levels it supports.
