The Snapdragon X Elite X1E-84-100 is a pretty fast ARM architecture processor (SoC) for use in Windows laptops. As the second-fastest X Elite chip in September 2024, the X1E-84-100 has 12 Oryon CPU cores running at up to 4.2 GHz, along with the 4.6 TFLOPS Adreno X1-85 iGPU, the 45 TOPS Hexagon NPU and an impressively fast LPDDR5x-8448 memory controller delivering over 100 GB/s of throughput. USB 4.0, TB 4 and PCIe 4 are all onboard, too.
Two slower Snapdragon X Elite flavors exist, known as the X1E-80-100 and X1E-78-100. In the meantime, the X1E-00-1DE is a special version of the X1E-84-100 aimed at system makers and software developers that has just slightly higher single-core and dual-core Boost clock speeds of 4.3 GHz but otherwise the same CPU/GPU/NPU configuration.
Architecture and Features
The Oryon cores (3 clusters of essentially identical cores; 12 threads) are mostly based on Nuvia IP and they reportedly make use of the ARM v8.7 microarchitecture. Much like modern AMD and Intel processors, the Snapdragon chip is compatible with USB 4 and thus with Thunderbolt 4 however it does not appear to support eGPUs as of September 2024.
Like most X Elite and X Plus processors, the X1E-84-100 is based on the larger die codenamed Hamoa. The processor is believed to have at least 12 PCIe 4 and 4 PCIe 3 lanes for connecting various kinds of devices. NVMe SSDs are supported with a throughput of up to 7.9 GB/s; furthermore, most laptops built around the chip are expected to have 16 GB of LPDDR5X-8448 RAM. There is also a 45 TOPS NPU present for accelerating AI workloads.
Performance
When all of the 12 cores are under load, they run at up to 3.8 GHz. The 4.2 GHz clock speed is only achievable under single-thread or dual-thread loads.
If the Galaxy Book4 Edge 16 review is any indication, the Snapdragon is almost as fast as the Core Ultra 7 155H in applications compiled for ARM while being up to 30% slower when executing x86 code.
A lot depends on how high the power limits of the system are, and how competent its cooling solution is.
Graphics
The 4.6 TFLOPS X1-85 iGPU has 1,536 unified shaders running at up to 1,500 MHz. It is reportedly (ChipsAndCheese) based on the significantly older Adreno 730 iGPU, rendering the X1-85 DX12-compatible but not DX12 Ultimate-compatible. AVC, HEVC and AV1 video codecs can be both hardware-decoded and hardware-encoded; with VP9, only decoding is possible. The highest monitor resolution supported is UHD 2160p rather than SUHD 4320p.
Its gaming performance is in many use cases almost as good as the Intel Arc 8 for reasonably playable experience in many 2023 and 2024 games such as Baldur's Gate 3 at 1080p on low graphics settings.
Power consumption
An X1E-84-100 can eat up to 80 watts depending on the system and the power profile chosen. This will differ from one laptop to another, with most designs expected to target the ~45 W sweet spot. The Samsung laptop that we finished testing in early September certainly does.
It must be said that the power consumption figures include RAM, unlike it is with most Intel and AMD chips.
The Qualcomm SoC is built with the TSMC N4P process for better-than-average, as of H2 2024, energy efficiency.
The Intel Core i5-1240P is a mid-range Alder Lake-P family SoC designed for use in ultra-light, ultra-thin (yet actively cooled) laptops. It was announced in early 2022 and it has 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 i5's P-cores are Hyper-Threading-enabled for a total of 16 threads when combined with its E-cores. The clock speeds range from 1.7 GHz to 4.4 GHz for the performance cluster and 1.2 GHz to 3.3 GHz for the efficient cluster. The shortcomings of this processor as compared with the slightly faster Core i5-1250P include the slightly lower iGPU clock speed and the limited vPro feature set ("Essentials" tier only, not allowing for remote device management).
Architecture
The i5 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little" Alder Lake core is supposed to be 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 Core i5-1240P's CPU cores enjoy access to 12 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 of RAM, for reference. Just like the other 12th Gen Intel Core processors, this Core i5 comes with the 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 (FCBGA1744 socket interface).
Performance
Multi-thread performance is most comparable to the Ryzen 5 5500U, Ryzen 5 5600U and, surprisingly enough, the Core i5-1250P, making the i5-1240P a great processor for most consumers. Content creators and gamers will be better served by an H-class CPU such as the mighty Core i7-12700H, though.
Thanks to its decent cooling solution and a long-term CPU power limit of 40 W, the NUC 12 Pro Kit NUC12WSBi5 is among the fastest systems built around the 1240P that we know of. It can be more than 2 times as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.
Graphics
The built-in graphics adapter in the form of the 80 EU Iris Xe running at up to 1.3 GHz has seen little change from what was built into certain Tiger Lake-UP3 processors, like an i5-1135G7, which is hardly a downside as this iGPU is loaded with modern features such as AV1 video decoding capability and SUHD 4320p monitor support. You can use up to 4 monitors simultaneously with this GPU, provided the laptop has the outputs required. The Xe isn't a stranger to a bit of casual gaming; that said, your mileage may vary depending on how high the Power Limits are and how capable the cooling solution of a laptop is. Expect something close to NVIDIA's MX250 or in other words, acceptable framerates in most games when playing at 1080p / Low settings. Fast RAM is a prerequisite for decent performance as the Iris Xe has to make do with no dedicated video memory.
Power consumption
The i5's base power consumption (also known as the default TDP value or Power Limit 1) is 28 W; its maximum Turbo power consumption (also known as the PL2) is not supposed to exceed 64 W. The "Minimum Assured" power consumption is fairly high at 20 W. All in all, an active cooling solution is a must for a CPU like this.
This 12th generation Intel chip is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency. Keep in mind that many 7 nm U-class AMD Ryzen 5000 chips are just as fast, or even faster than the i5 while sipping less juice.
The Snapdragon X Plus 8-core (X1P-42-100) is a relatively affordable ARM architecture processor for use in Windows laptops that was unveiled in Sep 2024. This Qualcomm SoC features 8 Oryon CPU cores running at up to 3.4 GHz, along with the 1.7 TFLOPS X1-45 iGPU and the 45 TOPS Hexagon NPU. The super-fast LPDDR5x-8448 memory controller, USB 4.0 support, TB 4 support and PCIe 4 support are all onboard as well.
Architecture and Features
The Oryon cores (2 clusters of essentially identical cores; 8 threads) are mostly based on Nuvia IP and they reportedly make use of the ARM v8.7 microarchitecture. Much like modern AMD and Intel processors, the Snapdragon chip is compatible with USB 4 and thus with Thunderbolt 4 however it does not appear to support eGPUs as of September 2024.
The X1P-42-100 is based on the smaller die codenamed Purwa, unlike most X Elite and X Plus processors. It is believed to have at least 8 PCIe 4 and 4 PCIe 3 lanes for connecting various kinds of devices. NVMe SSDs are supported with a throughput of up to 7.9 GB/s; furthermore, most laptops built around the chip are expected to have 16 GB of LPDDR5x-8448 RAM. There is also a 45 TOPS NPU present for accelerating AI workloads.
Performance
A lot depends on the power targets of a specific system, just like it is with AMD, Intel and Nvidia products. That being said, the average X1P-42-100 competes with older chips such as the Core i5-1245U when executing multi-threaded x86 code. With apps compiled specifically with Windows on ARM in mind, a Core i7-1360P-like performance level is to be expected which is not bad at all for what is supposed to be a budget CPU.
The 3.4 GHz clock speed is only achievable in single-thread workloads. When under multi-threaded load, the CPU cores will run at no more than 3.2 GHz.
Graphics
The X1-45 used here delivers up to 1.7 TFLOPS of performance. Unlike the much faster 3.8 TFLOPS and 4.6 TFLOPS X1-85 iGPUs, this little guy here has much fewer unified shaders and runs at lower clock speeds, too. Games put it a little behind the GeForce MX350; this kind of performance is sufficient for older games and sub-900p resolutions only.
AVC, HEVC and AV1 video codecs can be both hardware-decoded and hardware-encoded whereas with VP9, only decoding is possible. The highest monitor resolution supported is UHD 2160p.
Power consumption
Expect to see anything between 15 W and 30 W under long-term workloads depending on the system and the power profile chosen. The number includes RAM.
The SoC is built with TSMC's N4P process for better-than-average power efficiency, as of H2 2024.
