When it comes to understanding the performance and capabilities of a computer’s graphics processing unit (GPU), one of the most common questions that arises is about the amount of dedicated video random access memory (VRAM) it has. In the case of Intel Iris Plus Graphics, this question becomes even more pressing, as it’s a highly integrated GPU that shares system memory with the central processing unit (CPU). In this article, we’ll delve into the world of Intel Iris Plus Graphics and explore how many GB of dedicated memory it has, or rather, how it utilizes system memory to deliver impressive graphics performance.
What is Intel Iris Plus Graphics?
Before we dive into the specifics of Intel Iris Plus Graphics’ memory, it’s essential to understand what this technology is and how it works. Intel Iris Plus Graphics is a family of integrated GPUs developed by Intel, designed to provide improved graphics performance and power efficiency for laptops and ultrabooks. These GPUs are built into the CPU package, sharing the same silicon die, and utilize system memory (RAM) to perform graphics-related tasks.
The Iris Plus Graphics family was introduced in 2015, and since then, it has undergone significant improvements, with each new generation offering better performance, power management, and features. The latest iterations, such as the Iris Plus Graphics 640 and 650, are capable of delivering impressive graphics performance, rivaling that of some dedicated entry-level to mid-range graphics cards.
How Does Intel Iris Plus Graphics Utilize System Memory?
One of the unique aspects of Intel Iris Plus Graphics is its ability to dynamically allocate system memory for graphics processing. This approach allows the GPU to access a portion of the system’s RAM, known as the “Graphics Memory Allocation” or “GMA,” to perform graphics-related tasks.
The GMA is not a dedicated pool of memory allocated solely for graphics processing. Instead, it’s a shared resource that’s dynamically allocated and deallocated as needed. This approach enables the GPU to scale its performance based on the system’s workload and available resources.
When the GPU needs more memory, it can allocate a larger portion of the system’s RAM, up to a certain limit. This means that the amount of memory available to the GPU can vary depending on the system’s configuration, workload, and available resources.
Understanding the eDRAM Cache
In addition to the dynamic allocation of system memory, Intel Iris Plus Graphics also features an embedded dynamic random access memory (eDRAM) cache. This cache is a small, fast memory pool that’s dedicated to storing frequently accessed graphics data.
The eDRAM cache acts as a buffer between the GPU and system memory, reducing memory latency and improving overall graphics performance. The cache is typically 64MB or 128MB in size, depending on the specific Iris Plus Graphics model.
While the eDRAM cache is an essential component of Intel Iris Plus Graphics, it’s not the same as dedicated video memory. The cache is designed to augment the GPU’s performance, but it’s not a replacement for dedicated VRAM.
How Many GB of Memory Does Intel Iris Plus Graphics Have?
Now that we’ve explored how Intel Iris Plus Graphics utilizes system memory and the eDRAM cache, it’s time to answer the question: how many GB of memory does it have?
The short answer is that Intel Iris Plus Graphics does not have a fixed amount of dedicated video memory. Instead, it dynamically allocates system memory as needed, up to a certain limit.
The amount of memory available to the GPU depends on various factors, including:
- System configuration: The amount of system RAM, CPU model, and system architecture all impact the amount of memory available to the GPU.
- Workload: The type of graphics workload, such as gaming, video editing, or 3D modeling, affects the amount of memory required by the GPU.
- Iris Plus Graphics model: Different Iris Plus Graphics models have varying levels of performance and memory allocation capabilities.
In general, Intel Iris Plus Graphics can allocate anywhere from 256MB to 2GB of system memory for graphics processing, depending on the specific model and system configuration.
Iris Plus Graphics Models and Their Memory Allocation
Here’s a brief overview of some popular Iris Plus Graphics models and their memory allocation capabilities:
| Iris Plus Graphics Model | Memory Allocation (Max) |
|---|---|
| Iris Plus Graphics 640 | Up to 64GB (1.5 GB typical) |
| Iris Plus Graphics 650 | Up to 128GB (2 GB typical) |
| Iris Plus Graphics 655 | Up to 256GB (4 GB typical) |
Keep in mind that these are maximum values, and the actual memory allocation will vary depending on the system configuration and workload.
Comparing Intel Iris Plus Graphics to Dedicated Graphics Cards
When comparing Intel Iris Plus Graphics to dedicated graphics cards, it’s essential to understand the differences in their architecture and memory allocation.
Dedicated graphics cards, such as those from NVIDIA or AMD, have a fixed amount of dedicated video memory (VRAM). This VRAM is specifically designed for graphics processing and is not shared with the system’s RAM.
In contrast, Intel Iris Plus Graphics relies on system memory for graphics processing, which can impact its performance and capabilities.
Key differences between Intel Iris Plus Graphics and dedicated graphics cards:
- Dedicated VRAM vs. System Memory: Dedicated graphics cards have a fixed amount of VRAM, while Intel Iris Plus Graphics utilizes system memory.
- Performance: Dedicated graphics cards generally offer superior performance to Intel Iris Plus Graphics, especially in demanding graphics workloads.
- Power Consumption: Intel Iris Plus Graphics is designed for power efficiency, making it more suitable for battery-powered devices, while dedicated graphics cards often consume more power.
Conclusion
In conclusion, Intel Iris Plus Graphics does not have a fixed amount of dedicated video memory. Instead, it dynamically allocates system memory as needed, up to a certain limit. The amount of memory available to the GPU depends on the system configuration, workload, and Iris Plus Graphics model.
While Intel Iris Plus Graphics is not a replacement for dedicated graphics cards, it offers impressive performance and power efficiency for integrated GPUs. Understanding how it utilizes system memory and the eDRAM cache is crucial for optimizing its performance and capabilities.
When choosing a laptop or ultrabook, it’s essential to consider the specific Iris Plus Graphics model and its capabilities, as well as the system’s overall configuration, to ensure it meets your graphics requirements.
