AMD Radeon 820M vs NVIDIA RTX 1000 Mobile Ada Generation Comparison

Where Each One Wins

The benchmark data splits these two mobile graphics processors along clear architectural lines. The AMD Radeon 820M is an integrated graphics solution built for efficiency and low power, while the NVIDIA RTX 1000 Mobile Ada Generation is a discrete-class part with substantially more execution resources. The recorded data shows zero direct head-to-head benchmark wins for either part in the database, but the specification differences establish distinct application domains.

The AMD Radeon 820M wins in power efficiency, operating at a 15 W TDP compared to the NVIDIA part's 35 W TDP. That 20 W difference matters for thin-and-light portable systems where thermal headroom is limited. The Radeon also carries a higher boost clock at 2800 MHz versus 2025 MHz, which compensates somewhat for its smaller execution footprint in lightly threaded or clock-sensitive workloads.

The NVIDIA RTX 1000 Mobile Ada Generation wins decisively in raw compute throughput and memory bandwidth. Its 10.37 TFLOPS FP32 performance dwarfs the Radeon's 716.8 GFLOPS, a 14.5x advantage in raw shader math. The 192.0 GB/s memory bandwidth versus system-shared, system-dependent memory gives the NVIDIA part a massive edge in bandwidth-bound scenarios such as high-resolution texture streaming and large dataset manipulation. The RTX part also has dedicated 6 GB GDDR6 VRAM, whereas the AMD part relies entirely on shared system memory with bandwidth labeled as system dependent.

The data indicates the NVIDIA part wins in ray tracing and AI-accelerated workloads. It carries 20 RT cores and 80 tensor cores, while the AMD part has only 2 RT cores and no tensor core field. Any workload leveraging hardware ray tracing or tensor operations will favor the NVIDIA solution by a wide margin. The AMD part counters with a modern 4 nm process node versus 5 nm, though both come from TSMC foundry.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Radeon 820M uses the RDNA 3.5 architecture on the Krackan Point 2 chip, belonging to the Navi III IGP generation for Strix Point Mobile. It is manufactured on TSMC's 4 nm process. The NVIDIA RTX 1000 Mobile Ada Generation uses the Ada Lovelace architecture on the AD107 chip, part of the Ada-MW (x000A) generation, built on TSMC's 5 nm process.

Execution resource counts differ dramatically. The AMD part has 128 shading units, 8 texture mapping units, and 4 render output units. The NVIDIA part has 2560 shading units, 80 TMUs, and 48 ROPs. That represents 20x more shaders, 10x more TMUs, and 12x more ROPs on the NVIDIA side. The RTX part also includes 20 RT cores and 80 tensor cores, while the AMD part has just 2 RT cores and no tensor core field.

Transistor budgets reflect this resource gulf. The NVIDIA AD107 chip contains 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9M per mm². The AMD chip's transistor count and die size are recorded as unknown in the database, but its 4 nm process node indicates a more recent manufacturing generation. The AMD part's smaller execution footprint aligns with its integrated design role.

Memory architecture differs completely. The AMD Radeon 820M uses system-shared memory with no dedicated VRAM, no fixed bus width, and bandwidth that the database lists as system dependent. The NVIDIA RTX 1000 Mobile Ada Generation has 6 GB of GDDR6 memory on a 96-bit bus with 192.0 GB/s bandwidth. Memory clocks also differ: the AMD part lists system shared memory while the NVIDIA part runs at 2000 MHz with 16 Gbps effective data rate.

Clock behavior shows a different balancing act. The AMD part has a 400 MHz base clock and 2800 MHz boost clock, a wide dynamic range suited to aggressive power management. The NVIDIA part has a 1485 MHz base clock and 2025 MHz boost clock, a narrower range reflecting its higher idle baseline and larger compute array. Pixel throughput of 97.20 GPixel/s on the NVIDIA part versus 11.20 GPixel/s on the AMD part, and texture throughput of 162.0 GTexel/s versus 22.40 GTexel/s, confirm the NVIDIA part's fillrate advantage.

Both parts share PCIe 4.0 x8 bus interfaces and identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are integrated form factor (IGP slot width) with no power connectors and portable-device-dependent display outputs. The AMD part released on 2025-02-28, succeeding Navi II IGP. The NVIDIA part released on 2024-02-25, succeeding Ampere-MW and later succeeded by Blackwell-MW.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 820M and the NVIDIA RTX 1000 Mobile Ada Generation. Instead, the recorded specification data provides the basis for performance projection across several dimensions.

The largest measured gap appears in FP32 compute. The NVIDIA part delivers 10.37 TFLOPS, which is 14.5x the AMD part's 716.8 GFLOPS. In practical terms, any FP32-heavy workload such as general compute, physics simulation, or unoptimized rendering will complete dramatically faster on the NVIDIA part. The AMD part's FP16 performance matches its FP32 at 716.8 GFLOPS with a 1:1 ratio, while the NVIDIA part also runs FP16 at 10.37 TFLOPS with a 1:1 ratio, so the relative gap remains consistent across precision formats.

Fillrate metrics show a similar pattern. The NVIDIA part's pixel rate of 97.20 GPixel/s exceeds the AMD part's 11.20 GPixel/s by 8.7x. Texture rate of 162.0 GTexel/s versus 22.40 GTexel/s represents a 7.2x advantage. These figures directly impact resolution scaling and texture-heavy scene rendering. The NVIDIA part's 48 ROPs versus 4 ROPs, and 80 TMUs versus 8 TMUs, structurally support these fillrate differences.

Memory bandwidth presents the most one-sided comparison. The NVIDIA part's 192.0 GB/s dedicated bandwidth faces the AMD part's system-dependent shared memory, which has no fixed bandwidth figure in the database. The 6 GB GDDR6 allocation also removes any contention with CPU memory traffic, a factor that can significantly affect integrated graphics performance. The AMD part's bandwidth scalability depends entirely on the host system's memory configuration, making it a variable rather than a fixed specification.

Clock speed tells a different story. The AMD part boosts to 2800 MHz, 775 MHz higher than the NVIDIA part's 2025 MHz boost. This higher boost clock helps the AMD part in short-duration, lightly threaded workloads where its 128 shaders can run at maximum frequency without thermal constraints. However, the NVIDIA part's 2560 shaders operating at lower clocks still produce far higher aggregate throughput.

The ray tracing comparison is qualitative rather than quantitative. The NVIDIA part has 20 RT cores and 80 tensor cores, while the AMD part has 2 RT cores and no tensor core field. The database provides no RT performance scores, but the resource count difference indicates a wide capability gap for hardware-accelerated ray tracing and tensor-based operations such as DLSS-style upscaling.

The Verdict

The data supports a clear but context-dependent conclusion. The NVIDIA RTX 1000 Mobile Ada Generation is the superior performer across nearly every measured specification. Its 14.5x FP32 advantage, 8.7x pixel rate advantage, 7.2x texture rate advantage, and dedicated 6 GB GDDR6 memory with 192.0 GB/s bandwidth make it the choice for compute-intensive, graphically demanding, or memory-hungry workloads. The presence of 20 RT cores and 80 tensor cores extends that advantage into ray tracing and AI inference territory.

The AMD Radeon 820M wins the efficiency contest. At 15 W TDP versus 35 W, it consumes less than half the power budget. Its 4 nm process node is a generation ahead of the NVIDIA part's 5 nm node. The higher 2800 MHz boost clock suggests responsiveness in lightly threaded scenarios. For systems where battery life and thermal limits take priority over raw performance, the AMD part fits that role.

Users who need maximum graphical performance from a mobile platform should select the NVIDIA part. Users who prioritize power efficiency and operate within the constraints of an integrated graphics solution should select the AMD part. The database's percentile fields show both parts at the 50th percentile against all GPUs, but that figure reflects the database's current benchmark coverage, which records no direct head-to-head results for either part.
