Paul jacobs, CEO of Qualcomm, one of the world's largest mobile processor manufacturers, has been in China, the largest smartphone market on the planet, and has made very direct statements against the processor Samsung Exynos 5 Octa, stating that it is "a publicity stunt", and practically stating that it is misleading advertising. And it is that, in reality, what Jacobs does not like is that it is said that it has eight cores, when the performance of the smartphone will never be higher than that of a four-core one.
Samsung has introduced the world's most core mobile processors, right. Is named 5 Exynos Octa, and as its name suggests, it consists of eight cores inside. Actually, it's all true. They use technology big.LITTLE. And for those who haven't heard yet, what it actually does is introduce two processors into one. One of the processors is a high-performance quad-core processor, built with a ARM Cortex-A15. Next to it is another quad-core, lower performance, with architecture ARM Cortex-A7. Between the two, they make up the eight-core processor Samsung Exynos 5 Octa.
However, we must not be mistaken and think that it will work twice as fast as devices with a quad-core processor. Precisely the reason why Paul Jacobs has said that the 5 Exynos Octa It is just a publicity stunt, it is because at no time will the eight cores be used in Samsung devices, since only one processor can be used at that moment. When the other is changed and used, the old one stops working.
The CEO of the American company has taken the opportunity to explain that the reason why Samsung uses two processors is because it has not managed to get the quad-core processor with Cortex-A15 architecture, the high-performance one, to have a energy standardized, so that using only that processor would reduce autonomy in an incredible way.
Speaking in a way that everyone can understand, what Jacobs meant to say is that Samsung has failed to make a good enough processor, and that's why he had to use two. On top of that, instead of assuming it as something negative, he sells it as a technological triumph.
Be that as it may, the truth is that until we see the processor in operation, which will arrive, in all probability, inside a Samsung Galaxy S series, we will not be able to make any type of evaluation. It remains to be seen if Samsung has made a really good component, or if, as Jacobs says, it is just a "publicity stunt."
We have been talking with Qualcomm and, from the company, it ensures that the CEO of the company, Paul jacobs, at no time did it say in its statements that Samsung used misleading advertising or publicity gimmicks when it came to unveiling its new SoC. What this manager actually said is that focusing on the number of cores is misleading. Therefore his statements were taken out of context and it was because the original source did not make a correct translation from Chinese.
We have read it in UnwiredView.
big.LITTLE vs. HMP: Why all eight cores don't always work
The configuration big.LITTLE The original switches between sets of powerful and efficient cores, activating only one of them at a time. This explains why a Octa-core may not use all eight of its cores simultaneously. The evolution of this idea is Heterogeneous Multi-Processing (HMP), where the system can combine all cores at the same time or limit yourself to a single core for light tasks. This flexibility allows performance peaks when necessary and energy savings when not.
In practice, the key is in the system planner and thermal management: if the software doesn't distribute the load well or the chip heats up, overall performance is reduced. Hence, focusing only on the number of cores, as Qualcomm pointed out, can be misleading to interpret the real performance of a phone.
Beyond Cores: Caches and Multipliers
Performance also depends on elements such as cache hierarchy and the clock multiplier. Larger L1, L2, and L3 sizes reduce memory access and speed up operations.
- L1 cache: It is the fastest and closest to the core; increasing it here speeds up CPU-intensive tasks.
- L2 cache: when increasing, it improves the overall performance and reduces intermediate latencies.
- L3 cache: shared, helps coordinate nuclei and sustain high loads with fewer bottlenecks.
- Clock multiplier: controls the effective frequency of the CPU; with good energy management, it allows high peaks without penalizing the battery as much.
Exynos and Snapdragon today: CPU, GPU, NPU, and connectivity
In the Android ecosystem, Qualcomm Snapdragon y Samsung Exynos dominate the catalog. Snapdragon offers 600/700 (mid) and 800 (high) ranges, with advances in IA, GPU Adreno y 5GA significant leap forward was the 4nm architecture, with clear improvements in efficiency and power.
On the Samsung side, recent Exynos have evolved with 4nm nodes, more capable AI and graphics with collaboration from AMD. The Exynos 2200 It stood out for increasing performance in photography, gaming, and consumption. More recently, the Exynos 2400 goes up to a 10-core CPU (Cortex-X4 and A720/A520 clusters), a GPU xclipse 940 based on RDNA3 with ray tracing and an NPU with 14,7x improvement compared to the previous generation. It also supports camera sensors up to 320 SM and promises better thermal control.
When compared to a latest generation Snapdragon, such as the 8 January 3 with Adreno 750, the first benchmarks indicate a slight advantage for Qualcomm in synthetic scores (in tests such as AnTuTu around 1,81 M against 1,69 M). However, both offer ray tracing, advanced 5G, and powerful NPUs, so the real experience It will depend on the optimization of each brand.
Samsung's strategy alternates between Exynos and Snapdragon depending on the model and market. In recent generations, the models Ultra have opted for Qualcomm globally, while other Galaxy S models use Exynos in certain territories. This diversification helps the supply chain and fits with promises of long-term software support.
Sustained testing, battery and camera: what the tests say
In battery, they were measured more linear consumption on Qualcomm and a slight extra drain on Exynos in prolonged synthetic tests. Interestingly, some thermal tests reflected that the Snapdragon could reach higher temperatures under equivalent conditions, a reminder that performance, efficiency and warmth must be balanced.
In photography, the differences were subtle: each SoC's ISP can generate nuances of color different and variations in sharpness in certain details, but they do not determine the overall quality by themselves. In everyday use, both offer a very fluid, with no obvious gaps beyond extreme scenarios.
In terms of specific technical specifications, the following are also important: bandwidth and frequencyFor example, memory advantages have been seen for Snapdragon 8 Gen 2 over Exynos 1480 (64 GB/s vs 51,2 GB/s) and different maximum frequencies (up to 3,2 GHz on some Snapdragons vs 2,75 GHz on certain Exynos), although the 4nm manufacturing in modern Exynos it helps to make up ground in efficiency.
Looking at the whole, the discussion that ignited the 5 Exynos Octa serves to learn that the number of cores does not tell the whole story. The adoption of HMP, the hierarchy of hidden, the GPU, the NPU, bandwidth, and thermal management make the real difference. Today, both Qualcomm and Samsung offer top-tier solutions, and the optimal choice depends on the specific model and the tuning each manufacturer does.
