Intel Arc Graphics 24EU vs Intel Arc Pro B70 Comparison

The Verdict

The Intel Arc Graphics 24EU and the Intel Arc Pro B70 occupy opposite ends of the Intel graphics stack. The 24EU is an integrated graphics processor embedded in Arrow Lake-S desktop chips, while the Pro B70 is a dedicated, dual-slot professional accelerator built on the newer Xe2-HPG architecture. The database's metrics place the 24EU at the 3rd percentile of all GPUs, with an average benchmark score of 733. The Pro B70, by contrast, sits at the 50th percentile, though it has no recorded benchmark scores in the database, meaning its performance must be inferred from its architectural specifications rather than direct measurements.

The Verdict is straightforward from the recorded data. The Intel Arc Graphics 24EU is for systems where a discrete GPU is not needed, it uses system shared memory, draws 65 W, and is an IGP with motherboard-dependent outputs. The Pro B70 is a workstation-class card for compute and professional workloads, carrying 32 GB of GDDR6 memory, a 256-bit bus, 608.0 GB/s of bandwidth, and a 230 W TDP. The 24EU's closest rivals in the database, the Intel Arc Graphics 32EU and 64EU, all score identically at 733, while the Pro B70 has no nearest rivals listed, reflecting its unique position in the database.

Architecture Differences

The two parts come from different Intel generations. The 24EU uses the Xe-LPG architecture, part of the Arc Graphics (Arrow Lake) generation, built on a 3 nm TSMC process. The chip itself, Arrow Lake-S, contains 17,800 million transistors on a 243 mm² die, yielding a transistor density of 73.3M per mm². The Pro B70 uses the Xe2-HPG architecture from the Battlemage (Pro Series) generation, fabricated on a 5 nm TSMC process with a larger 368 mm² die. Transistor counts for the Pro B70 are not recorded in the database.

The execution resources differ enormously. The 24EU has 192 shading units, 12 texture mapping units, and 6 raster output units. The Pro B70 has 4096 shading units, 256 TMUs, and 128 ROPs. The Pro B70 also includes 32 ray tracing cores, while the 24EU lists no RT cores at all. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists despite the massive hardware gap.

Clock behavior also separates them. The 24EU runs at a 300 MHz base and a 2000 MHz boost. The Pro B70 runs at a 2280 MHz base and a 2800 MHz boost, meaning even its base clock exceeds the 24EU's boost clock. Memory configuration is the most striking divergence. The 24EU relies on system shared memory with system-dependent bandwidth. The Pro B70 uses 32 GB of GDDR6 at 2375 MHz, 19 Gbps effective, on a 256-bit bus, delivering 608.0 GB/s of bandwidth.

The Pro B70's physical design reflects its discrete nature. It measures 267 mm by 110 mm by 39 mm, uses a dual-slot cooler, requires a single 8-pin power connector, and recommends a 550 W system power supply. It connects via PCIe 5.0 x16 and offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The 24EU is an IGP with a Ring Bus interface, no power connectors, and motherboard-dependent display outputs.

Where Each One Wins

Based on the recorded data, the Intel Arc Graphics 24EU wins in power efficiency and platform simplicity. Its 65 W TDP is dramatically lower than the Pro B70's 230 W. It requires no additional power connectors, no slot space, and no dedicated memory purchases, since it uses system shared memory. For desktop systems where the CPU's integrated graphics suffice, the 24EU is the logical choice.

The Pro B70 wins decisively in raw throughput. Its pixel rate is 358.4 GPixel/s versus 12.00 GPixel/s for the 24EU, a 29.9x advantage. Its texture rate is 716.8 GTexel/s versus 24.00 GTexel/s, a 29.9x advantage. Its FP32 compute is 22.94 TFLOPS versus 768.0 GFLOPS, a 29.9x advantage. Its FP16 compute is 45.88 TFLOPS versus 1.536 TFLOPS, also a 29.9x advantage. The 32 GB of dedicated GDDR6 memory with 608.0 GB/s of bandwidth has no equivalent on the 24EU, which relies on system memory.

The Pro B70 also wins in memory capacity and bandwidth for large datasets. The 24EU's system-shared memory means its bandwidth is system dependent, with no fixed figure recorded. The Pro B70's fixed 608.0 GB/s bandwidth is a concrete, measurable advantage for memory-intensive workloads. The Pro B70's 32 ray tracing cores give it hardware acceleration for ray-traced workloads, a capability the 24EU lacks entirely.

The release dates place the Pro B70 later in the market, with a launch MSRP of 949 USD. The 24EU's launch MSRP is not recorded in the database.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc Graphics 24EU and the Intel Arc Pro B70. The head-to-head benchmark table is empty, and the wins counters show 0 for both parts. Instead, the comparison must rely on the 24EU's recorded benchmark and the Pro B70's architectural specifications.

The 24EU's only recorded benchmark is 3DMark Steel Nomad DX12, where it scores 733. Its nearest rivals in the database are the Intel Arc Graphics 32EU and 64EU, both with identical average scores of 733, showing a 0% delta. The AMD Radeon HD 6470M scores 723, which is 1.4% below the 24EU. The NVIDIA GeForce GT 415M scores 751, which is 2.4% above the 24EU. These small deltas indicate that the 24EU sits in a narrow performance band among low-end parts, within roughly 2% of its closest competitors.

The Pro B70 has no benchmark entries and no nearest rivals, so its performance cannot be compared numerically against any other GPU in the database. Its 50th percentile ranking, however, places it far above the 24EU's 3rd percentile. This percentile gap, combined with the architectural specifications, suggests the Pro B70 operates in a completely different performance class.

The compute throughput figures show the scale of the difference. The 24EU delivers 768.0 GFLOPS of FP32 performance. The Pro B70 delivers 22.94 TFLOPS of FP32 performance. In FP16, the 24EU delivers 1.536 TFLOPS, while the Pro B70 delivers 45.88 TFLOPS. Both use a 2:1 ratio for FP16 relative to FP32. The Pro B70's texture rate of 716.8 GTexel/s and pixel rate of 358.4 GPixel/s dwarf the 24EU's 24.00 GTexel/s and 12.00 GPixel/s. Each of these figures represents a roughly 30x advantage for the Pro B70.

The clock speed comparison reinforces the gap. The 24EU boosts to 2000 MHz, while the Pro B70 boosts to 2800 MHz, a 40% higher boost clock. The Pro B70's base clock of 2280 MHz is higher than the 24EU's boost clock of 2000 MHz. The Pro B70 also has 21.3x more shading units (4096 versus 192), 21.3x more TMUs (256 versus 12), and 21.3x more ROPs (128 versus 6).

The memory subsystem is where the Pro B70 separates itself most clearly. The 24EU has no dedicated memory, no fixed bus width, and no fixed bandwidth figure. The Pro B70's 32 GB GDDR6 pool on a 256-bit bus delivers 608.0 GB/s. This is not a small incremental gain; it is the difference between a processor borrowing system memory and a dedicated card with its own high-bandwidth memory pool. For workloads that saturate memory bandwidth, this distinction is fundamental.

The only area where the 24EU shows an advantage is power draw. At 65 W, it consumes 28.3% of the Pro B70's 230 W TDP. It also requires no power connectors, no slot space, and no external power supply recommendation. The Pro B70 lists a suggested PSU of 550 W. The 24EU's IGP form factor and motherboard-dependent outputs make it suitable for compact systems, while the Pro B70's dual-slot, 267 mm length, and 1x 8-pin connector require a full desktop chassis with adequate cooling and power delivery.

The database's percentile rankings summarize the class difference. The 24EU at the 3rd percentile is among the lowest-performing GPUs recorded. The Pro B70 at the 50th percentile sits at the median of all GPUs. The 24EU's nearest rivals are all within 2.4% of its score, indicating that it competes with legacy mobile parts from over a decade ago. The Pro B70's nearest rivals list is empty, indicating that no other GPU in the database has similar recorded properties, which is consistent with its professional positioning rather than a mainstream gaming or integrated part.
