AMD Ryzen 7 6800U vs Intel Core i7-1260P vs AMD Ryzen 5 6600U

AMD Ryzen 7 6800U

The AMD Ryzen 7 6800U is a processor for thin and light laptops based of the Rembrandt generation. The R7 6800U integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.7 (guaranteed base clock) to 4.7 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. Compared to the similar R7 6800H, the 6800U offers a lower base clock speed and a lower TDP.

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

A big novelty is the integrated GPU Radeon 680M, that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.2 GHz. It should be the fastest iGPU of all at the time of announcement.

Performance

The average 6800U in our database easily shoulders its way towards the best of the best, trading blows with the Core i7-1270P, the Core i7-11850H and the Ryzen 7 PRO 6850H as far as multi-thread benchmark scores are concerned. Throw everything you can at this little guy. He'll take it all and ask for more.

Thanks to its decent cooling solution and a long-term CPU power limit of more than 20 W, the Mercury EM680 is among the fastest systems built around the 6800U that we know of. It can be at least 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 7 series chip has a default TDP, also known as the long-term power limit, of 15 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, a proper cooling solution is a must.

The R7 6800U is manufactured on the 6 nm TSMC process for higher-than-average, as of mid 2023, energy efficiency.

Intel Core i7-1260P

The Intel Core i7-1260P is an upper mid-range 28 W Alder Lake CPU designed for use in ultra-light laptops. It was announced in early 2022 and it features 4 performance cores as opposed to the 6 cores of the top-of-the-line i7-1280P (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled for a total of 16 threads when combined with the E-cores. The clock speeds range from 2.1 GHz to 4.7 GHz for the performance cluster and 1.5 GHz to 3.4 GHz for the efficient cluster. The i7's shortcomings as compared to Intel Core i7-1270P include the marginally lower clock speeds and limited vPro feature set ("Essentials" tier only, not allowing for remote device management).

Architecture

The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "littile" Alder Lake core is supposed to be just as fast as a Skylake core (as found in the venerable Core i7-6700HQ among other options) which is six years old at this point. All of an Core i7-1260P's CPU cores enjoy access to 18 MB of L3 cache. The integrated memory controller supports various memory types up to LPDDR5-5200, DDR5-4800, LPDDR4x-4267 or DDR4-3200; Intel recommends using no more than 64 GB, for reference. Just like the other 12th Gen Intel Core processors, Intel Core i7-1260P comes with Thread Director which is a new functionality designed to help Windows 11 decide which cores to use for what workload for best performance and efficiency possible. Hardware acceleration of AI algorithms is supported via GNA 3.0 and DL Boost (via AVX2). PCI-Express 5.0 support has not found its way into Alder Lake P processors, so users will have to be content with PCI-Express 4.0 for the time being. Four PCI-Express 4 lanes allow for a read/write rate of up to 7.9 GB/s, provided a suitably fast NVMe SSD is used.

Please note this is not a user-replaceable CPU. It gets soldered permanently on to the motherboard (BGA1744 socket interface).

Performance

Multi-thread performance is most comparable to the Ryzen 7 5800U, Ryzen 7 PRO 5850U and also the Core i5-11260H. This makes the 1260P a great little CPU - one capable of punching above its weight.

Thanks to its decent cooling solution and a long-term CPU power limit of 35 W, the Asus ExpertBook B5 Flip B5602FBN is among the fastest laptops featuring the 1260P that we know of. It can be about 2 times as fast in CPU-bound workloads as the slowest system built around the same chip in our database (as of August 2023).

Graphics

The built-in graphics adapter in the form of the 96 EU Iris Xe running at up to 1.4 GHz has seemingly seen no change from what was built into certain Tiger Lake-UP3 processors, like a i7-1165G7. Which is hardly a downside as this iGPU is loaded with modern features such as AV1 video decoding capability and SUHD 4320p monitor support. Up to 4 monitors can be used simultaneously with this graphics adapter. Its gaming performance is bound to be tied to how high the Power Limits and how good the cooling solution of a laptop are; expect something close to NVIDIA's MX350 or in other words, acceptable framerates in most games when playing at 1080p / Medium settings. Fast RAM is a prerequisite for decent performance as the Iris Xe has to make do with no dedicated video memory. Last but not the least, we discovered that the GPU utilization when playing YouTube UHD 2160p60 videos is higher than it was with Tiger Lake chips.

Power consumption

The i7's base power consumption (also known as the default TDP or Power Limit 1) is 28 W, with 64 W being its maximum Intel-recommended Turbo power consumption (also known as the PL2). Its "Minimum Assured" power consumption sits at 20 W. All in all, an active cooling solution is a must for a CPU like this one here.

The i7-1260P is manufactured on Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency. Despite that, many 7 nm U-class AMD Ryzen 5000 parts are less power-hungry while being as fast (or even faster, depending on the workload) as the i7.

AMD Ryzen 5 6600U

The AMD Ryzen 5 6600U is a processor for thin and light laptops based of the Rembrandt generation. The Ryzen packs six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.9 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm process at TSMC. Compared to the similar R5 6600H, the 6600U offers a lower base clock speed and a lower TDP.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600U only offers the small Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock rate.

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

Performance

The average 6600U in our database matches the Ryzen 7 5800U in multi-thread performance, making this Ryzen 5 series chip a great CPU for most activities as of mid 2023.

Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

Power consumption

This Ryzen 5 series chip has a default TDP, also known as the long-term power limit, of 15 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, that's too much to allow for passively cooled designs.

The R5 6600U is manufactured on TSMC's 6 nm manufacturing process for good, as of mid 2023, energy efficiency.
