Yes—in the reported GFXBench OpenGL run, Intel’s Arc 140T scored about 62% higher than Lunar Lake’s Arc 140V. The Arc 140T reached 178.3 frames per second, compared with 110.3 FPS for a 16GB Arc 140V system. But this was a leaked synthetic result, not a controlled laptop review, so it does not prove a universal 62% gaming advantage.
The reported results
The benchmark data, attributed to Michael (@miktdt), showed the Arc 140T completing 11,056 frames at an average of 178.3 FPS. The 16GB Arc 140V result reached 6,839 frames at 110.3 FPS, while an 8GB Arc 140V configuration recorded 6,613 frames at 106.7 FPS.
| GPU | Reported memory configuration | Total frames | Average FPS | Comparison |
|---|---|---|---|---|
| Arc 140T | Reported 16GB system configuration | 11,056 | 178.3 | Baseline |
| Arc 140V | 16GB system configuration | 6,839 | 110.3 | About 61.9% of the 140T result |
| Arc 140V | 8GB system configuration | 6,613 | 106.7 | About 59.9% of the 140T result |
Using the reported FPS figures, the Arc 140T was approximately 61.7% faster than the 16GB Arc 140V and approximately 67.1% faster than the 8GB result. The available coverage identifies the test as a GFXBench OpenGL result, but does not independently establish every subtest setting, resolution, driver, or system power limit. It should therefore not be presented as a complete GFXBench suite comparison.
The leak first received major coverage in October 2024. It is not a newly discovered August 2026 retail benchmark, and later drivers or laptop implementations may perform differently. (Tom’s Hardware; ITNetwork)

What is Intel Arc 140T?
Arc 140T is a mobile integrated GPU associated with Intel’s Arrow Lake-H and Arrow Lake-HX processors. Intel preview material listed Arc 140T graphics alongside Core Ultra 9 285H and related H-series products. (Intel H-series preview material)
Third-party specifications generally list eight Xe cores, 128 execution units or equivalent shader resources, eight ray-tracing cores, and XMX support. Notebookcheck categorizes the GPU as Xe+, while other coverage uses terms such as Xe-LPG+. These are third-party architectural classifications rather than an official Intel architecture label, so Arc 140T should not be described as a confirmed Xe2 GPU. (Notebookcheck specifications)
What is Arc 140V?
Arc 140V is Lunar Lake’s top integrated GPU and is officially associated with Core Ultra 200V processors. It uses Intel’s newer Xe2 graphics architecture. Intel’s Lunar Lake documentation describes the platform as incorporating a new Xe2 GPU, while its product and support pages identify Arc 140V graphics for relevant processors. (Intel Lunar Lake architecture fact sheet; Intel ARK)
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Lunar Lake is designed around efficiency, thin-and-light systems, and battery life. Arc 140V does not have dedicated VRAM: like other integrated GPUs, it uses shared system memory. Consequently, an “8GB” or “16GB” label normally describes the laptop’s system memory configuration, not a separate pool of graphics memory.
Why can the older-looking 140T win?
The apparent contradiction is the most important part of the result: a GPU generally described as Xe+ or Xe-LPG+ beat the newer Xe2-based Arc 140V in this particular workload. That does not mean the older architecture is universally better. Several platform and test variables can explain the outcome.

More power headroom
Arrow Lake-H/HX laptops generally operate with more thermal and electrical headroom than the highly power-constrained systems built around Lunar Lake. A higher-power platform can allow its integrated GPU to sustain higher clocks or receive a larger share of package power.
This is a likely explanation, not a proven one. The leak does not provide a controlled same-wattage comparison, and a 140T in a performance-oriented laptop is not directly comparable with a 140V in a low-power ultrabook.

Different clock speeds
Peak and sustained GPU clocks can substantially affect an integrated GPU result. Cooling quality, firmware, fan modes, package power allocation, and temperature limits all influence whether a GPU maintains its advertised behavior. The available benchmark information does not disclose enough detail to isolate clock speed as the cause.
Memory configuration
Integrated graphics depend heavily on system memory bandwidth and latency. LPDDR5x versus DDR5, memory data rate, dual-channel operation, timings, firmware settings, and capacity can all affect performance.
The different 8GB and 16GB Arc 140V results show that configuration matters, but they do not prove that capacity alone caused the gap. The labels do not represent dedicated VRAM, and the systems may differ in other ways.

OpenGL and driver behavior
GFXBench OpenGL may favor a particular driver stack, compiler path, or architectural behavior. A large OpenGL advantage may shrink, disappear, or reverse in DirectX 11, DirectX 12, Vulkan, or a specific game engine. Driver versions also matter, especially when engineering samples or early benchmark entries are involved.
Recommended Free Tools
Architecture-specific behavior
Xe2 and the Xe+/Xe-LPG+ implementation associated with Arc 140T have different front-end, cache, compiler, and driver characteristics. Equal or similar reported core counts do not make two integrated GPUs equivalent. Core count alone cannot account for the performance difference—or predict performance across every workload.
What the GFXBench result proves—and what it does not
The strongest defensible statement is:
In the reported GFXBench OpenGL run, the Arc 140T was about 62% faster than a 16GB Arc 140V system.
That establishes a meaningful workload-specific lead in a published benchmark leak. It does not establish that:
- Arc 140T laptops are 62% faster in games overall.
- Arc 140T is faster at the same power limit.
- Arc 140T is more power-efficient.
- Arc 140T is faster in DirectX 12 or Vulkan.
- Every Arc 140T laptop will beat every Arc 140V laptop.
- The 8GB Arc 140V configuration is inherently slower than every 16GB configuration.
- The result represents final retail hardware.
- Arc 140T has a newer or more advanced architecture than Arc 140V.
Engineering samples can be misidentified, use unusual firmware, or run non-final drivers. Even retail systems with the same processor and GPU can produce different results because of cooling, memory, power profiles, and manufacturer tuning.

What it could mean for gaming
GFXBench is useful as an indicator of graphics behavior, but it is not a substitute for a broad gaming test suite. A meaningful gaming comparison would need the same memory configuration, comparable laptop power limits, documented driver versions, and identical game settings.
It should also include 1080p results across DirectX 11, DirectX 12, and Vulkan where available, along with frame-time data rather than average FPS alone. Plugged-in and battery testing would be valuable too, because low-power laptops may substantially change their graphics behavior away from the charger.
Intel’s XeSS technology may improve perceived performance in supported games, but upscaling or frame-generation results should not be confused with native-rendering performance. (Intel XeSS)
Which laptop platform should you choose?
For buyers, the GPU name is only one part of the decision. Check the exact processor, sustained package power, cooling design, memory type and speed, channel configuration, driver, display resolution, and the laptop’s plugged-in and battery profiles.
Arc 140T is the more logical choice when:
- Sustained graphics throughput matters more than maximum battery life.
- The laptop uses a higher-power Arrow Lake-H or HX processor.
- It has fast dual-channel or LPDDR5x memory and strong cooling.
- The price is lower than a comparable Lunar Lake model.
- Your workloads respond well to its driver and architecture.
Arc 140V is the more logical choice when:
- Battery life, low fan noise, and portability are priorities.
- The laptop is primarily a thin-and-light productivity system.
- You value Lunar Lake’s efficiency-focused platform and Xe2 feature set.
- Independent testing confirms good sustained performance at the laptop’s actual power limit.
A poorly cooled Arc 140T laptop can underperform a well-tuned Arc 140V system. Conversely, a high-power 140T machine with fast memory may deliver considerably more sustained graphics performance than a low-power Lunar Lake design. Buyers should therefore use the GFXBench result as a clue, not as a replacement for reviews of the exact laptop model.
Verdict
The Arc 140T clearly won the reported comparison: 178.3 FPS versus 110.3 FPS for the 16GB Arc 140V, a lead of roughly 62%. But the evidence demonstrates workload-specific OpenGL throughput, not a universal gaming or efficiency advantage.
The likely explanation combines platform power, clocks, memory, cooling, firmware, drivers, and OpenGL-specific behavior. Lunar Lake’s Arc 140V remains a newer Xe2 design optimized within an efficiency-focused platform, while Arc 140T benefits from the potentially higher power envelope of Arrow Lake-H/HX systems. Until controlled retail-laptop testing matches those variables, the leak should be treated as evidence of Arc 140T potential—not a definitive ranking of every Arrow Lake and Lunar Lake laptop.
