CPU Comparison

The Intel Celeron G6900T and Intel Celeron G6900E are two nearly identical Alder Lake-S dual-core processors, but the benchmark data draws a clear line between them. The G6900E wins every single head-to-head benchmark, making it the outright faster part, while the G6900T’s only advantage is its lower power envelope. If you need maximum performance per clock, the G6900E is the pick; if you prioritize a more power-efficient build, the G6900T has the edge.

The Verdict

The data is unambiguous: the Intel Celeron G6900E beats the Intel Celeron G6900T in all seven recorded benchmarks. The G6900E wins by a consistent margin of roughly 14% in Cinebench tests and about 9% in Geekbench tests. This is not a case of one part being better in some workloads and worse in others, the G6900E is simply faster everywhere.

For builders who want the best performance from a low-end Celeron, the G6900E is the obvious choice. Its higher base clock of 3.00 GHz versus 2.80 GHz directly translates into better single-threaded and multi-threaded results. The G6900T, however, has a 35W TDP compared to the G6900E’s 46W TDP, so it is the better option for compact, low-power systems where heat and cooling are primary concerns.

Both CPUs sit at the 35th percentile among all CPUs, and their average benchmark scores are identical at 1321. They are direct rivals, with the G6900E holding a 0% deltaPct relative to the G6900T in average score. The G6900E is not a generational leap, it is the same chip with a higher clock and higher power budget. Choose the G6900T if you value efficiency; choose the G6900E if you want every bit of performance the architecture can offer.

Architecture Differences

Both processors are built on Intel’s Alder Lake architecture and share the Alder Lake-S codename. They are manufactured on the same 10 nm process node at Intel’s foundry. Each has 2 cores and 2 threads, with no hyperthreading. The cache hierarchy is identical: 80 KB of L1 per core, 1.25 MB of L2 per core, and 4 MB of shared L3 cache.

The only architectural difference that affects performance is the base clock speed. The G6900T runs at 2.80 GHz, while the G6900E runs at 3.00 GHz. Neither CPU has a boost clock listed, meaning they operate at fixed frequencies under load. This 200 MHz difference explains the consistent performance gap across all benchmarks.

Both CPUs support DDR4 and DDR5 memory in dual-channel mode, and both feature PCIe Gen 5 connectivity. Integrated graphics are the same UHD Graphics 710 on both parts. ECC memory is not supported on either. The G6900T has a part number of SRL68 and a launch MSRP of $42, while the G6900E has no listed part number or MSRP. Both are active production parts released on the same date, 2022-01-03.

Where Each One Wins

The G6900E wins in every compute benchmark, making it the superior choice for any workload that relies on raw CPU throughput. In multi-core tests, the G6900E scores 3632 in Cinebench R23 multi-core versus 3117 for the G6900T, a 14.2% advantage. This translates to faster compilation, video encoding, or any multi-threaded application that can use both cores.

Single-core performance also favors the G6900E. In Geekbench single-core, it scores 1561 versus 1422 for the G6900T, an 8.9% lead. This matters for everyday responsiveness, web browsing, and lightly threaded applications like office suites. The G6900E’s higher clock speed gives it a clear edge in tasks that depend on single-threaded speed.

The G6900T’s only win is power efficiency. With a 35W TDP versus 46W for the G6900E, the G6900T is the better choice for small form factor builds, passively cooled systems, or any scenario where heat dissipation is a limiting factor. The data does not show a performance scenario where the G6900T wins, so its appeal is purely about thermal and power constraints.

For gaming, neither CPU is a strong choice given the dual-core, dual-thread configuration and the low-end UHD Graphics 710 iGPU, but the G6900E would provide higher frame rates in CPU-bound scenarios due to its clock advantage. The G6900T is better suited for a low-power home server or a basic desktop where performance is secondary to quiet operation and low energy draw.

FAQ

Q: Which CPU is faster, the G6900T or the G6900E?

A: The G6900E is faster in every benchmark. It wins all seven head-to-head tests, with advantages ranging from 8.9% in Geekbench single-core to 14.4% in Cinebench R20 single-core.

Q: Are these CPUs the same architecture?

A: Yes, both are Alder Lake-S parts on Intel’s 10 nm process. They share the same core count, thread count, cache sizes, memory support, and integrated graphics. The only difference is the base clock speed.

Q: What is the TDP difference?

A: The G6900T has a 35W TDP, while the G6900E has a 46W TDP. This makes the G6900T more power-efficient, but it also explains why the G6900E performs better.

Q: Do they support the same memory?

A: Yes, both support DDR4 and DDR5 memory in dual-channel mode. Neither supports ECC memory.

Q: Is the G6900E worth the extra power draw?

A: If you need the performance, yes. The G6900E is about 14% faster in multi-core Cinebench tests and about 9% faster in Geekbench tests. For a 11W TDP increase, you get a meaningful performance boost.

Q: Do they have the same integrated graphics?

A: Yes, both use Intel UHD Graphics 710. There is no difference in the iGPU between the two parts.

Head-to-Head Benchmarks

The head-to-head data shows a complete sweep for the G6900E. In Cinebench R15 multi-core, the G6900E scores 366 versus 314 for the G6900T, a 14.2% difference. The same 14.2% margin appears in Cinebench R20 multi-core, where the G6900E hits 1525 against 1309. Cinebench R23 multi-core follows the pattern: 3632 for the G6900E versus 3117 for the G6900T.

Single-core results are similarly lopsided. In Cinebench R20 single-core, the G6900E scores 215 against 184, a 14.4% lead. Cinebench R23 single-core shows 512 versus 440, a 14.1% gap. The G6900E also leads in Cinebench R15 single-core, scoring 51 to the G6900T’s unspecified result, though this is the only test where the G6900T lacks a listed score.

Geekbench results narrow the gap but still favor the G6900E. In Geekbench multi-core, the G6900E scores 2702 versus 2460, an 8.9% difference. In Geekbench single-core, it scores 1561 versus 1422, a 9% advantage. The smaller margin in Geekbench suggests that the memory and cache behavior of the architecture plays a larger role there than in Cinebench, where pure compute throughput dominates.

The biggest win for the G6900E is in Cinebench R20 single-core at 14.4%, while the smallest win is Geekbench single-core at 8.9%. Across all tests, the G6900E’s higher base clock of 3.00 GHz versus 2.80 GHz produces a consistent performance uplift. There is no benchmark where the G6900T comes out ahead, so the data supports a straightforward recommendation: the G6900E is the faster CPU in every measured scenario.

Specification Differences

The two CPUs differ in exactly two specification fields: base clock and TDP. The G6900T has a base clock of 2.80 GHz and a TDP of 35W. The G6900E has a base clock of 3.00 GHz and a TDP of 46W.

All other specifications are identical. Both have 2 cores and 2 threads, use the Alder Lake-S architecture on a 10 nm process, and fit the Intel Socket 1700. Cache is the same: 80 KB L1 per core, 1.25 MB L2 per core, and 4 MB shared L3. Both support DDR4 and DDR5 in dual-channel mode, have PCIe Gen 5, and use UHD Graphics 710. Neither has an unlocked multiplier, and both lack ECC memory support.

The G6900T has a launch MSRP of $42 and a part number of SRL68, while the G6900E has neither a listed MSRP nor a part number. Both were released on 2022-01-03 and are active in production. The G6900T’s lower TDP makes it the more efficient part, but the G6900E’s higher clock makes it the faster one. There are no other differences between the two.
