Core Architecture and Specifications Showdown
Alright, let’s get down to the nitty-gritty of what makes these two processors tick. It’s not just about clock speeds, you know? The way a chip is built, its internal layout, and how it handles data all play a huge role in how it performs.
Intel Lunar Lake Core Configuration
Intel’s Lunar Lake chips, like the Core Ultra 7 155H we’re looking at, are built using a hybrid approach. They’ve got a mix of cores designed for different tasks. Specifically, you’ll find 4 new "Lion Cove" Performance-cores (P-cores) and 4 "Skymont" Efficient-cores (E-cores). These aren’t your old-school cores; Intel claims the Lion Cove cores offer a decent bump in performance over previous generations, and the Skymont cores are supposed to be way more efficient, like a 68% improvement. It’s interesting that none of these cores have Hyper-Threading, which is a bit different from what some other companies are doing.
AMD Ryzen 7 8840HS Core Details
On the AMD side, the Ryzen 7 8840HS uses AMD’s Zen architecture. It typically features 8 cores and 16 threads, meaning each core can handle two tasks at once thanks to Simultaneous Multi-Threading (SMT), which is AMD’s version of Hyper-Threading. These cores are designed to balance strong performance with good power efficiency for everyday tasks and more demanding workloads. AMD usually packs a good amount of cache memory onto these chips too, which helps speed up data access.
Manufacturing Process and Cache Hierarchy
Both processors are made using advanced manufacturing processes. Intel’s Lunar Lake is built on a 3nm process, which is pretty cutting-edge and helps with power efficiency and performance density. AMD’s Ryzen 7 8840HS is typically manufactured on a 4nm process. The cache hierarchy is also important. Cache is like a super-fast, small memory right on the chip that stores frequently used data. Both processors have different levels of cache (L1, L2, and L3), and the amount and speed of this cache can significantly impact how quickly the processor can access information and get things done. Intel’s Lunar Lake, for instance, has 12MB of L3 cache on the models we’re discussing, while AMD’s Ryzen 7 8840HS also typically offers a substantial L3 cache, often around 16MB, which can be a real advantage in certain applications.
Performance Benchmarks: CPU and Multitasking
Alright, let’s get down to brass tacks and see how these two processors actually perform when you’re doing stuff. We’re talking about everyday tasks, heavy lifting, and everything in between. It’s not just about raw numbers; it’s about how that translates to your experience.
Single-Core Performance Metrics
When a single core is doing the heavy lifting, like in many older applications or certain demanding tasks, you want a processor that can really push ahead. We looked at benchmarks like Cinebench 2024’s single-core test, which gives us a good idea of how fast each chip can handle a single thread. The Intel Core Ultra 7 155H shows some solid numbers here, often scoring around 119 points. While the AMD Ryzen 7 8840HS also performs well, the Intel chip generally edges it out slightly in these specific single-threaded scenarios. This means for tasks that don’t split work across many cores, the Intel might feel a bit snappier.
Multi-Core Processing Power
Now, this is where things get interesting for modern computing. Most applications today can use multiple cores, and when you’re multitasking – say, running a virtual machine while compiling code or editing a video – you need all the cores you can get. Benchmarks like Geekbench 5.5’s multi-core test and Cinebench 2024’s multi-core test show how these processors handle parallel workloads. The AMD Ryzen 7 8840HS often shows its strength here, typically pulling ahead in multi-core scores. This suggests that for heavy multitasking or productivity applications that are good at using many cores, the Ryzen might offer a bit more grunt. It’s a close race, though, and the specific workload can really change the outcome.
Real-World Application Throughput
Benchmarks are great, but what about real-world use? We also looked at tests that simulate actual application usage, like file compression with 7-Zip or rendering tasks. These tests often give a more practical view of performance. For instance, in tasks like file archiving, the Ryzen 7 8840HS has historically shown strong performance, often completing these tasks quicker. The Intel Core Ultra 7 155H, however, is no slouch and can keep up in many scenarios, especially when its integrated graphics are also brought into play for certain accelerated tasks. It’s worth noting that user reviews often reflect a positive sentiment towards the Ryzen chips for their consistent performance, with the AMD Ryzen 7 8840HS having a higher average rating in many user surveys. Ultimately, the best choice depends on your primary use case.
Integrated Graphics Capabilities
When we talk about integrated graphics, we’re looking at what the processor can do without needing a separate, dedicated graphics card. This is super important for laptops, especially for everyday tasks, watching videos, and even some light gaming.
Intel Arc Graphics 140V Performance
Intel’s new Arc Graphics 140V is a pretty big step up from older integrated solutions. It’s built on an "Xe² architecture" and can hit clock speeds up to 2,050 MHz. It also packs 8 ray tracing units, which is neat for newer games that use that technology. This iGPU supports DirectX 12 Ultimate, meaning it’s ready for modern graphics features. Plus, it’s got hardware decoding for a bunch of video formats like H.266 VVC, H.265 HEVC, H.264 AVC, AV1, and VP9. This makes watching high-resolution videos smooth sailing. You can even hook up three 4K monitors at once, which is great for multitasking.
Gaming and Media Playback
So, how does it actually perform? For gaming, Intel says you can expect to play most 2023 and 2024 games at 1080p on low settings or better. In tests, games like Ghost of Tsushima hit over 30 frames per second, and Baldur’s Gate 3 got close to 40 fps. This puts it ahead of AMD’s Radeon 780M, though not quite matching the top-tier Radeon 890M. For media, its strong codec support means smooth playback for pretty much any video you throw at it.
Ray Tracing and Video Codec Support
Here’s a quick rundown of what the Arc Graphics 140V brings to the table:
- Ray Tracing: Includes 8 dedicated ray tracing units for more realistic lighting and reflections in supported games.
- Video Decoding: Hardware acceleration for popular codecs including H.266 VVC, H.265 HEVC, H.264 AVC, AV1, and VP9.

- DirectX 12 Ultimate: Full support for the latest graphics API, enabling advanced features.
Power Consumption and Thermal Design
When you’re looking at laptop processors, how much power they use and how hot they get is a pretty big deal. It directly affects battery life and how long you can push the laptop before it starts to slow down. Let’s break down what the Intel Core Ultra 7 155H and the AMD Ryzen 7 8840HS are doing in this department.
Intel Core Ultra 7 155H TDP
Intel’s Core Ultra 7 155H is designed with efficiency in mind, especially for thin and light laptops. Its typical Thermal Design Power (TDP) is set around 28W, but it can boost up to 115W for short bursts when needed. This means it can handle demanding tasks without immediately overheating, but it’s also built to sip power during lighter workloads. Laptops using this chip often have a base TDP around 20-30W, with some configurations allowing for higher sustained power draw, up to 39W in certain models, which can help performance but will also increase heat and fan activity.
AMD Ryzen 7 8840HS Power Draw
The Ryzen 7 8840HS, on the other hand, has a configurable TDP that typically ranges from 35W to 54W. This higher base TDP suggests it’s geared towards sustained performance, potentially at the cost of slightly more power consumption compared to the Intel chip’s base setting. However, AMD’s processors are known for their efficiency, so even with a higher TDP, they can still offer good battery life. The actual power draw will vary a lot depending on the laptop’s specific design and cooling.
Efficiency Under Load
So, who’s the winner here? It’s not a simple answer. For everyday tasks like web browsing or document editing, both chips are pretty efficient. You’ll likely see good battery life from laptops equipped with either. The real difference shows up when you start pushing them hard. The Intel chip, with its lower base TDP, might be more conservative and run cooler and quieter for longer periods under moderate load. The AMD chip, with its higher TDP ceiling, might offer better sustained performance in heavy multitasking or gaming scenarios, but it will likely generate more heat and require more robust cooling. Ultimately, the laptop manufacturer’s implementation – the cooling system and power management settings – plays a huge role in how these processors perform in the real world regarding heat and power draw.
AI Acceleration and Neural Processing
Intel’s AI Boost NPU
Intel’s Core Ultra processors are packing some serious AI punch with their integrated Neural Processing Unit (NPU), which they call "AI Boost." This dedicated hardware is designed to handle AI tasks much more efficiently than the CPU or GPU alone. Think of it as a specialized brain for artificial intelligence workloads. For the Core Ultra 7 155H, Intel claims its NPU can churn out up to 47 TOPS (Trillions of Operations Per Second). That’s a pretty big number, and it means things like AI-powered noise cancellation, background blur in video calls, and even more complex AI applications can run smoother and faster without draining your battery as quickly. It’s all about offloading those AI jobs to the right tool for the job.
AMD’s Ryzen AI Capabilities
AMD isn’t playing catch-up here either. Their Ryzen 7 8840HS also features a dedicated AI engine, branded as "Ryzen AI." This NPU is built on the XDNA architecture and is designed to accelerate AI inferencing tasks. While the exact TOPS figure can vary depending on the specific configuration and workload, AMD has been pushing the envelope with its AI performance. The goal is similar to Intel’s: to provide a dedicated hardware accelerator for AI, making everyday tasks smarter and more responsive. This means features like AI-assisted content creation, improved system responsiveness, and potentially new AI-driven software experiences are all on the table.
AI TOPS Comparison
When we look at the raw numbers, both Intel and AMD are making big claims about their AI processing power. The Intel Core Ultra 7 155H, with its AI Boost NPU, is stated to reach up to 47 TOPS. AMD’s Ryzen 7 8840HS, with its Ryzen AI engine, also aims for high performance in AI tasks, though specific TOPS figures can be a bit more fluid depending on the benchmark and how it’s implemented.
Here’s a quick look at what’s on offer:
- Intel Core Ultra 7 155H: Up to 47 TOPS (NPU)
- AMD Ryzen 7 8840HS: Significant AI acceleration capabilities (specific TOPS vary by implementation)
It’s important to remember that TOPS is just one metric. How well these NPUs are utilized by software and the actual performance in real-world AI applications are what truly matter. Both companies are working with developers to make sure their AI hardware gets put to good use, so we should see more AI-accelerated features popping up in our favorite apps soon.
Connectivity and Platform Features
Thunderbolt and USB Support
When you’re looking at new processors, how they connect to everything else is pretty important. Both the Intel Core Ultra 7 155H and the AMD Ryzen 7 8840HS are pretty well-equipped here, but Intel has a slight edge with its native Thunderbolt 4 support.
