Early Geekbench listings did reveal real AMD RDNA 4 hardware and pointed toward the 56- and 64-compute-unit configurations later used by the Radeon RX 9070 and RX 9070 XT. They did not, however, provide a reliable forecast of gaming speed. The first August 2024 sample produced only about 33,000 in OpenCL, while later February 2025 entries showed much higher Vulkan and OpenCL results under uncontrolled pre-release conditions.
AMD ultimately launched the first desktop RDNA 4 cards as the Radeon RX 9000 series—not the widely expected RX 8000 series—on February 28, 2025. The final specifications confirmed much of the leaked core and memory information, while also showing why an engineering-sample benchmark should not be treated as a product review.
The two Geekbench leak waves
The reports commonly grouped under “RDNA 4 Geekbench leaks” came from two different periods and should not be treated as one continuous test run.
August 2024: GFX1201/Navi 48 engineering sample
A Geekbench Browser entry identified as GFX1201 was associated in reporting with AMD’s larger Navi 48 RDNA 4 design. The listing was reported on August 26, 2024, when desktop products were still expected to carry Radeon RX 8000 branding. It reportedly showed 28 listed compute units, about a 2.1 GHz clock and 16 GB of memory. Some coverage interpreted the 28 listed units as a partial or otherwise not fully enabled configuration rather than the final product count.

Its OpenCL result was approximately 33,000, an unusually low number for a GPU expected to sit above mainstream products. The result is best understood as evidence of an immature engineering sample, incomplete configuration or early driver state—not as evidence that finished RDNA 4 cards would perform at that level.
ComputerBase’s report, Dexerto’s coverage and Wccftech’s report all treated the specifications as leaked information rather than AMD-confirmed product data.
February 2025: likely RX 9070-series samples
Later Geekbench entries were associated with the products that became the Radeon RX 9070 XT and RX 9070. Reports identified a 64-CU configuration with 4,096 stream processors as the likely XT and a 56-CU configuration with 3,584 stream processors as the likely non-XT model. Both were reported with 16 GB of VRAM.

| Radeon RX 9070 | 158,520 | 140,842 |
These were leaked submissions, not AMD-certified results. The systems, drivers and firmware were not controlled across entries, so the figures should be read as individual observations rather than a laboratory ranking.

What those scores actually suggested
Vulkan
In the cited dataset, the leaked RX 9070 XT’s Vulkan score of about 177,395 was close to the listed GeForce RTX 4070 Super result. The RX 9070’s approximately 158,520 was lower. The same comparison placed the XT below the listed RTX 5070 Ti and Radeon RX 7900 XTX results.

OpenCL
The RX 9070 XT’s reported OpenCL score of about 179,178 was near the cited RTX 4070 Super result, while the RX 9070 reached approximately 140,842. The XT remained below the RTX 5070 Ti in that particular table.
Those comparisons apply only to the named Geekbench API and dataset. They do not establish game frame rates, ray-tracing speed, creator-app performance, power efficiency or a general win over any competing card.
Why Geekbench could not predict gaming performance
- Different workloads: Vulkan and OpenCL measure API compute behavior, not a representative mix of game engines.
- Driver maturity: Pre-release drivers can lack optimizations, contain bugs or use temporary workarounds.
- Unequal test platforms: The leaked entries used different CPUs, motherboards, memory, BIOS settings and driver versions.
- Sample identity: A public submission can be misidentified, modified or run on hardware that is not a final retail board.
- Incomplete feature coverage: Geekbench does not comprehensively exercise RDNA 4’s ray-tracing, AI and game-specific improvements.
The most defensible interpretation is that the results proved working RDNA 4 samples existed and offered clues about their configurations. They were weak evidence for final gaming performance.

What AMD later confirmed
AMD announced RDNA 4 and the first Radeon RX 9000 desktop cards on February 28, 2025. Official specifications broadly validated the leaked core-count and memory story.
| Specification | Radeon RX 9070 XT | Radeon RX 9070 |
|---|---|---|
| Architecture/process | RDNA 4, 4 nm | RDNA 4, 4 nm |
| Compute units | 64 | 56 |
| Stream processors | 4,096 | 3,584 |
| Ray accelerators | 64 | 56 |
| AI accelerators | 128 | 112 |
| Memory | 16 GB GDDR6 | 16 GB GDDR6 |
| Memory interface | 256-bit | 256-bit |
| Infinity Cache | 64 MB, third generation | 64 MB |
| Boost clock | Up to 2,970 MHz | Up to 2,520 MHz |
| Total board power | 304 W | 220 W |
| Recommended PSU | 750 W | 650 W |
The figures come from AMD’s official specifications and its RX 9000 quick-reference guide. The XT uses two 8-pin power connectors; the cited guide lists up to 640 GB/s of memory bandwidth for that card.

| 56 compute units | Confirmed for the RX 9070. |
| 64 compute units | Confirmed for the RX 9070 XT. |
| 16 GB of memory | Confirmed for both launch cards. |
| Approximately 2.1 GHz sample clock | Not a final retail clock; official boost targets are higher and differ by model. |

| Approximately 33,000 early OpenCL score | Not representative of finished retail behavior. |
At the time, AMD’s next generation was widely expected to be called Radeon RX 8000. AMD ultimately launched the first desktop RDNA 4 cards as the Radeon RX 9000 series, as stated in its February 28, 2025 announcement.

What this means for buyers now
RX 9070 XT
The RX 9070 XT is the higher-performance launch option, with a 304 W board-power target and a 750 W recommended power supply. AMD’s launch SEP was $599 on February 28, 2025; that historical figure is not a current street-price quote. Check the card’s physical dimensions, connector arrangement and your case and PSU before buying.
RX 9070
The RX 9070 keeps 16 GB of GDDR6 and the 256-bit interface while reducing board power to 220 W and the recommended PSU to 650 W. Its launch SEP was $549, also dated February 28, 2025. It is the more practical choice when power, thermals or case capacity matter more than the XT’s additional compute resources.
Other RDNA 4 options
The RX 9060 XT launched in 8 GB and 16 GB versions. A launch review reported prices of $299 and $379 respectively, but those are historical launch signals rather than August 2026 street prices. The 16 GB model is less constrained by demanding textures and future VRAM requirements.
AMD also lists an RX 9070 GRE with 48 compute units, 12 GB of memory and a 192-bit interface. Availability is market-dependent, so do not assume it is sold in every country.
How to evaluate a GPU leak responsibly
- Confirm that the entry appeared in the public Geekbench Browser and inspect the reported device identifier.
- Determine whether the board is an engineering sample, a review sample or a retail product.
- Record the driver version, BIOS and test platform rather than comparing scores without context.
- Keep Vulkan and OpenCL results separate; they are not interchangeable measures.
- Look for repeated submissions and later official specifications before treating a detail as established.
- For a purchase decision, use controlled 1080p, 1440p and 4K game tests, frame-time data, ray-tracing results, power measurements and current pricing.
Geekbench’s OpenCL browser and Vulkan browser are useful for checking submissions. They are supplementary evidence, not substitutes for controlled reviews. Buyers using compute software should also verify exact support in ROCm’s GPU documentation; appearing in Geekbench does not imply CUDA or ROCm compatibility.
Bottom line
The RDNA 4 Geekbench story was valuable as an early hardware sighting. It correctly pointed toward 56 and 64 compute units and 16 GB configurations that later became the RX 9070 and RX 9070 XT. The scores themselves were too dependent on immature software, engineering samples and uncontrolled test systems to predict gaming performance. With both cards now established retail products, controlled game reviews, power requirements, current prices and software support are more useful than the original leak rankings.
