Intel Core i7-620UE

The Intel Core i7-620UE is a 32nm Westmere-based mobile processor from the Arrandale generation, released on January 6, 2010. It is a dual-core part with four threads, a base clock of 1067 MHz, and a boost clock of 2.13 GHz. With an 18W TDP, it targets ultra-low-power mobile and embedded systems. The database places it at the 50th percentile among all CPUs tracked, indicating a median performance level. Its launch MSRP was $278.

Benchmark Performance

The FACT PACK lists no recorded benchmark scores for the Core i7-620UE. The benchmarks array is empty, and the average benchmark score is 0. This absence of data means that direct performance comparisons against specific rivals are not possible from the database. However, the percentile field provides a useful anchor: the CPU sits at the 50th percentile of all CPUs tracked. This means that, in the aggregate database, it performs better than half of all processors and worse than the other half. Given its dual-core, four-thread design and modest clock speeds, this median placement is consistent with its position as an entry-level mobile part from its era.

The base clock of 1067 MHz is extremely low, but the boost clock of 2.13 GHz is exactly double that value. This large boost range suggests that the CPU can deliver significantly higher single-thread performance when thermal and power headroom allow. In multi-threaded workloads, the two physical cores with four threads will limit performance compared to modern quad-core or higher parts. Without benchmark scores, the data does not allow for precise delta percentages against rivals. The 50th percentile is the only comparative metric available. This percentile is a relative measure across the entire database, not a specific rival comparison.

The lack of benchmark data means that any performance assessment must rely on the architectural and clock specifications. The Westmere architecture, on a 32nm process, was a mature design at its release. The 382 million transistors on an 81 mm² die indicate a relatively small chip, which aligns with its low power envelope. The 4 MB of shared L3 cache is a reasonable amount for a dual-core part. The memory bandwidth of 17.1 GB/s via dual-channel DDR3 is typical for the platform. These specifications together paint a picture of a CPU that was competent for its time but is now far behind modern parts. The 50th percentile ranking is a blunt instrument, but it does confirm that this is not a high-performance part by any stretch of the database's historical record.

Power and Thermals

The TDP of 18W is a defining characteristic of the Core i7-620UE. This is an ultra-low-power classification, placing it in the same class as many modern laptop chips. For cooling, an 18W TDP implies that a simple low-profile cooler or even a passive heatsink in a well-ventilated chassis would be sufficient. The data does not specify a cooler size, but the low TDP means that large, high-airflow coolers are unnecessary. The 32nm process node contributes to the low power draw, as does the modest transistor count of 382 million. The die size of 81 mm² is small, which helps with heat dissipation.

The boost clock of 2.13 GHz will increase power consumption above the 18W base, but the CPU is designed to stay within a tight thermal budget. The integrated HD Graphics (Ironlake) also draws from the same TDP envelope, meaning that graphics-intensive tasks will reduce the available power for the CPU cores. For a mobile platform, this is a critical consideration. The end-of-life status means that this part is no longer manufactured, but its thermal characteristics remain relevant for systems that still use it. The 18W TDP is a hard number from the FACT PACK, and it dictates the entire thermal design of any system using this CPU.

The low TDP also has implications for system size and noise. A passive or semi-passive cooling solution is plausible, which is ideal for fanless industrial boxes or thin-and-light laptops. The 32nm process is relatively advanced for its time, and the small die size helps to concentrate heat in a small area, making it easier to manage. The memory controller and integrated graphics are also on the same die, so the 18W TDP covers the entire package. For anyone designing a system around this CPU, the thermal solution does not need to be elaborate. A standard heatsink with a low-speed fan would easily handle the heat output, even under sustained boost loads.

Single-Thread vs Multi-Thread Behavior

The Core i7-620UE has 2 cores and 4 threads, with a base clock of 1067 MHz and a boost clock of 2.13 GHz. The boost clock is exactly double the base clock, which is a significant spread. In single-threaded workloads, the CPU will attempt to boost to 2.13 GHz, providing a substantial performance uplift over the base clock. This is important for older applications that rely on a single core. However, the absolute clock speed of 2.13 GHz is low by modern standards, so single-thread performance will be limited. The 4 MB of shared L3 cache helps to reduce memory latency for single-threaded tasks, as the entire cache is available to one core when needed.

In multi-threaded workloads, the CPU uses its 4 threads to handle parallel tasks. The dual-core design with Hyper-Threading allows for some parallel execution, but the physical core count of 2 is a bottleneck. The 4 MB of shared L3 cache is shared between the two cores, which can lead to contention if both cores are heavily active. The memory bandwidth of 17.1 GB/s is shared across the dual-channel DDR3 bus, and this bandwidth is modest by modern standards. For workloads that scale well with cores, this CPU will lag behind quad-core or higher parts. The 50th percentile ranking suggests that its overall performance is average, but this is an aggregate measure that does not differentiate between single-thread and multi-thread performance.

The large boost range means that the CPU is designed to run at a low base clock to save power, then ramp up when needed. This behavior is typical of ultra-low-power mobile parts. For real-world usage, tasks like web browsing, document editing, and light spreadsheet work will benefit from the boost clock. Heavier multi-threaded tasks like video encoding or 3D rendering will be limited by the dual-core design. The single-thread boost of 2.13 GHz is the CPU's strongest asset, but it is still a low absolute frequency. The dual-core design is the primary limitation for any modern workload that uses more than two threads.

How It Compares

The FACT PACK lists no nearest rivals for the Core i7-620UE. The nearestRivals array is empty, meaning the database does not provide specific competitor names, scores, or delta percentages. Therefore, a direct comparison against named rivals is not possible from the provided data. The only comparative metric available is the 50th percentile across all CPUs. This percentile indicates that the CPU sits exactly at the median of the entire database. It is neither a standout performer nor a bottom-tier part. Without rival data, any statement about being ahead of or behind a specific processor would be unsupported.

Given the empty rival list, the analysis must rely on the architectural specifications. Compared to modern mobile CPUs, which typically have 6 or 8 cores and much higher clock speeds, the 620UE's dual-core design and 2.13 GHz boost are severely outdated. However, compared to other CPUs from its own 2010 release era, it was a mid-range part. The 50th percentile placement suggests that it was a typical processor for its time. The lack of rival data is a notable gap, but it does not prevent a general assessment. The percentile is a relative measure across all CPUs, so it can serve as a proxy for comparison. It tells us that the 620UE is not an outlier in either direction; it is a perfectly average processor in the database's historical record.

The absence of nearestRivals also means that no deltaPct values are available. This prevents any quantitative comparison such as "30% ahead of X" or "20% behind Y." The only number we have is the 50th percentile, which is a rank, not a performance delta. For a benchmark database, this is a significant limitation. However, the architectural data (cores, clocks, cache, memory bandwidth) provides a qualitative basis for understanding its position. It is a low-power dual-core part, so it will be slower than any modern quad-core or higher in multi-threaded tasks, and slower than any modern part in single-threaded tasks due to its low clock speed.

Who Should Consider It

The Core i7-620UE is an end-of-life mobile processor with an 18W TDP and integrated HD Graphics. Its performance, as indicated by the 50th percentile, is adequate for basic office productivity. Tasks such as word processing, spreadsheet management, email, and web browsing will run acceptably, especially when the CPU boosts to 2.13 GHz. The dual-core design with four threads can handle light multitasking. However, it is not suited for modern gaming, as the integrated Ironlake graphics are very weak and the CPU clock is low. For gaming, a dedicated GPU is required, and this CPU would bottleneck any modern graphics card.

For content creation, such as video editing or 3D rendering, the dual-core design is a severe limitation. These workloads are heavily multi-threaded and require many cores. The 4 MB L3 cache and 17.1 GB/s memory bandwidth are insufficient for large datasets. The CPU would be suitable for legacy industrial control systems, embedded applications, or thin-client terminals where low power consumption and ECC memory support are more important than raw performance. The ECC memory support is a notable feature, as it allows for error-correcting memory, which is valuable in reliability-critical environments.

The 50th percentile ranking means that half of all CPUs in the database are faster. For anyone considering this part today, it would only make sense for specific niche applications where its low TDP and ECC support are paramount, and where performance is not a priority. It is not a good choice for a general-purpose desktop or laptop. The integrated graphics are only suitable for basic display output, not for any graphical work. The low clock speeds and dual-core design make it unsuitable for any modern software that expects a baseline level of performance. It is a relic of its era, best suited for tasks that have not changed since 2010.

Platform and Compatibility

The Core i7-620UE uses the Intel BGA 1288 socket. This is a ball-grid array, meaning the CPU is soldered directly to the motherboard. As a result, there is no upgrade path for the processor itself. The CPU is end-of-life, so new motherboards are not produced for it. The platform supports DDR3 memory in a dual-channel configuration, with a memory bandwidth of 17.1 GB/s. ECC memory is supported, which is a distinguishing feature for a mobile part. The memory bus is dual-channel, so two sticks of DDR3 are recommended for optimal bandwidth.

The PCIe support is Gen 2, which is an older standard. This limits the bandwidth available for expansion cards and storage devices. The integrated graphics are HD Graphics (Ironlake), which are built into the CPU. The architecture is Westmere, with the codename Arrandale. The process node is 32nm, and the CPU contains 382 million transistors on an 81 mm² die. The release date was January 6, 2010, and the launch MSRP was $278. The multiplier is locked, so there is no overclocking capability. The part number is SLBPASLBXJQ4MN.

The platform is obsolete by modern standards. The BGA socket means the CPU cannot be replaced. The DDR3 memory is outdated, and PCIe Gen 2 is slow compared to Gen 4 or Gen 5. For anyone with an existing system using this CPU, the only upgrade path is to replace the entire motherboard and CPU, which would require a new memory type as well. The ECC support is the only feature that might justify its continued use in specific industrial or server-like roles. The dual-channel DDR3 bus, while adequate for its time, is a bottleneck for modern memory-intensive applications. The 17.1 GB/s bandwidth is a hard limit that cannot be exceeded.
