That suggests a value of around $100 for a 5600g processor priced near $80,000. From a budget standpoint, Intel seems to be offering the best deal since they recognize the lower quality and match their pricing accordingly. It's hard to compete with the $13.6k and $14.7k price points.
Here are some revised versions of your text with varied phrasing and structure:
1. A few points to note here... AMD tends to perform better in certain scenarios while underperforming in others. Check out some reviews on Gamers Nexus for more insight. Steve does an excellent job incorporating efficiency charts. The AMD 7000-X processors aren’t always the most efficient, but they still hold their own. He highlighted how much power these CPUs consume, especially at stock settings. They use significantly less energy than Intel in both single-thread and multi-thread performance. Still, AMD 7000-NON-X models excel in default configurations. Steve also demonstrated the energy consumption metrics for rendering the GN logo, showing that AMD Non-X CPUs outperform Intel in this regard. This efficiency is notable not just for gaming, but also for everyday tasks. For instance, the 7800X-3D stands out as one of the most efficient processors available. This advantage extends beyond gaming—it applies to productivity too. The 7900X-3D and 7950X-3D feature a CCD chip without 3D V-Cache, allowing cores to operate at higher speeds while consuming less power. Meanwhile, the 7800X-3D uses a single CCD core, which is kept at a lower voltage and temperature to protect the sensitive cache. This design enables it to draw around 80 watts under full load, nearly half the power of Intel’s mid-range i5-13600K. Still, it delivers strong performance without sacrificing speed. @BabaGanuche, your review is helpful—AMD CPUs could even surpass these numbers with techniques like undervolting, which they handle exceptionally well. In fact, they might achieve even better efficiency than what’s shown here. One reason AMD CPUs can get hot is the IHS. To maintain compatibility with AM4 coolers on the AM5 platform, AMD thickened the IHS on the Ryzen 7000 series. This helps bridge the gap and ensures proper thermal contact. Why does this matter? Because a thicker IHS traps heat, and higher temperatures mean increased power consumption. As temperature rises, so does electrical resistance. This follows basic principles of physics and thermodynamics. A hotter CPU requires more voltage and energy to maintain the same speed.
2. JaysTwoCents pointed out that the 7950X was modified with a prototype lapping tool, reducing the IHS by 0.8mm. This adjustment cut temperatures by 12°C once optimized. However, the process was rushed, resulting in subpar performance. If properly executed with the Thermal Grizzly tool, a more efficient CPU could be achieved. This highlights how small tweaks can significantly impact efficiency.
3. It’s worth noting that AMD CPUs often struggle with heat management, partly due to the IHS design. To keep AM4 compatibility with AM5, AMD increased the thickness of the IHS on the Ryzen 7000 chips. This helps maintain contact with existing coolers but also traps heat. Higher temperatures mean greater power draw, which directly affects efficiency. As per the laws of physics, heat increases resistance, making cooling more critical. This is why AMD’s mid-range CPUs, like the i5-13600K, can outperform Intel in efficiency despite similar specifications.
Let me know if you'd like further adjustments!
I never claimed Intel is straight up better, and I mentioned this before in the same thread. Both have strong CPUs, but power efficiency really depends on the workload. I began this discussion because some thought AMD was more efficient just because of their node advantage, but Intel has a thicker IHS. With Meteor Lake, Intel is moving up two points, aligning node performance, and I think you’ll see a different perspective. I don’t believe my research is lacking here.
I appreciate your question. Where exactly do you find the 50W idle figure? Your experience with the 7900 (dual CCD) shows it draws 10-12W when idle—meaning just browsing and opening tabs. It has a TDP of 65W without EPO, but reaches 90W under full load. Applying a 50W idle figure would be quite high. Currently, 11 cores are in sleep mode and one operates at 600MHz; occasionally two cores idle at 400MHz. This means it won<|pad|>'s load would remain relatively low, so a 50W idle wouldn't be excessive. Many reviews also mention idle power usage, which is something that's commonly discussed. It seems AMD isn't significantly worse than Intel in this regard, at least not for everyday use. You're right about the importance of load and idle power—it affects cooling design, PSU size, and overall system efficiency. Even with monitors, memory usage, and inefficiencies, the 8W difference you mentioned is minor compared to cooling and power delivery concerns. It would be nice to see a reduction in that 8W, but it probably isn't the main reason for choosing between the two brands.
