Panther Lake’s Xe3 integrated GPU has surfaced in an early benchmark leak, but it is not Intel’s Celestial GPU. The reported result is a Geekbench compute score—not a gaming benchmark—and Intel has not confirmed a consumer Celestial desktop card or its specifications and launch timing.
What the Panther Lake benchmark actually shows
Tom’s Hardware reported a leaked Geekbench 6 Compute OpenCL score of 52,946 for a system using Intel’s Core Ultra X7 358H. That was the highest score in the report, and the outlet said scores rose as the tester reran the benchmark. The result is preliminary, produced with non-final software, and does not establish how a retail laptop will perform.
OpenCL is a compute workload, not a game test. The number cannot be read as a frame rate or as a general ranking of Panther Lake laptops. Cross-system comparisons in the report also do not control for differences such as power limits, cooling, memory, drivers, or software revisions. Intel is identified as tending to lag in this benchmark, another reason not to treat the score as a complete measure of graphics capability. Tom’s Hardware’s report of the leak
Panther Lake uses Xe3, not Celestial
Intel announced Panther Lake as its Core Ultra Series 3 client platform, with an Arc GPU configuration of up to 12 Xe cores. The graphics architecture in Panther Lake is Xe3. That naming distinction matters: Intel representative Tom Petersen told PC Gamer that Panther Lake Xe3 “isn’t” Celestial. He described Xe3P as the first instance of work from the Celestial architecture team, not as confirmation of a consumer Celestial gaming card.

- Robust Power & Thermal Design: Engineered with 125W base power and 250W max turbo power to sustain high‑intensity
Petersen also said Intel had announced a data-center design using Xe3P, but declined to discuss unreleased desktop products. The statements do not establish a consumer Celestial GPU’s name, specifications, or launch date. PC Gamer’s interview with Tom Petersen
Intel’s Panther Lake graphics claim is not a benchmark result
Intel said Panther Lake’s new Arc GPU would deliver more than 50% faster graphics performance than the previous generation. This is a vendor comparison, not an independently verified result for every laptop, game, or configuration. Actual performance will depend on the system and workload. Intel said the platform would have configurations with up to 12 Xe cores. Its 2025 announcement planned the first SKU to ship before the end of that year, with broad availability beginning in January 2026. Intel’s Panther Lake announcement

What Xe3’s architecture details do—and don’t—tell you
GamersNexus reported that Xe3 increases the number of Xe cores per render slice, raises L1 cache from 192 KB to 256 KB, and increases L2 cache. For the maximum 12-core Panther Lake configuration, it described 16 MB of L2 cache. Intel representative Tom Petersen said selected applications saw 17% to 36% less traffic toward memory when moving from an 8 MB to a 16 MB L2 setup.

GamersNexus also reported Intel’s Xe3 depth-writes microbenchmark as showing a 7.4× relative performance improvement, while cautioning that Xe2 and Xe3 test configurations differed. A result from that specific microbenchmark should not be translated into a prediction that games will run 7.4 times faster. GamersNexus’ Xe3 architecture coverage

How to interpret “Intel Celestial GPU early benchmarks”
That phrase is a search query, not evidence of a Celestial benchmark. The X7 358H leak concerns Panther Lake’s Xe3 integrated graphics. Intel’s public comments connect Xe3P with work by the Celestial architecture team, but they do not confirm a consumer Celestial gaming product. Intel’s Xe architecture documentation provides technical background; it does not, by itself, establish such a product.
For a laptop buying decision, wait for independent tests of retail systems and compare game-specific results alongside power limits, cooling, memory configuration, drivers, battery behavior, and display. The single leaked OpenCL score is not enough to rank Panther Lake laptops as a class.
