The release of Google DeepMind's Gemma 4 has sent shockwaves through the local AI community, offering frontier-level reasoning on consumer-grade hardware. For developers and enthusiasts, the newest gemma 4 inference speed benchmark results reveal a massive generational leap over Gemma 3, particularly in math and coding tasks. Whether you are running a compact edge device or a high-end workstation, understanding the gemma 4 inference speed benchmark is crucial for selecting the right model size and quantization level for your specific hardware.
In this guide, we break down the performance of the four primary model sizes—31B, 26B (MoE), 4B, and 2B—across various platforms including the NVIDIA RTX 4070 Ti, RTX 3090, and the Grace Blackwell-powered DGX Spark. We will examine how these models handle real-world tasks like code generation and live data synthesis while maintaining low latency.
Gemma 4 Model Family Overview
The Gemma 4 lineup is designed to be versatile, ranging from massive dense transformers to highly efficient Mixture-of-Experts (MoE) variants. Google has optimized these models to fit within the VRAM constraints of modern GPUs, making local inference more accessible than ever in 2026.
| Model Variant | Parameters | Type | Primary Use Case |
|---|---|---|---|
| Gemma 4 31B | 31 Billion | Dense | Frontier reasoning, complex coding |
| Gemma 4 26B-A4B | 26 Billion | MoE (4B Active) | High-speed agentic workflows |
| Gemma 4 E4B | 4 Billion | Effective/Edge | Mobile, Jetson Orin Nano, Raspberry Pi |
| Gemma 4 E2B | 2 Billion | Effective/Edge | Ultra-low power devices, IoT |
The 31B model is the flagship of the open-weight collection, currently ranking among the top three open models on the Arena AI leaderboard. However, for those prioritizing speed, the 26B MoE variant is often the better choice, as it only activates 3.8 billion parameters during the inference phase.
Gemma 4 Inference Speed Benchmark: Hardware Performance
When evaluating a gemma 4 inference speed benchmark, hardware architecture plays a defining role. Recent tests show that while consumer RTX cards excel at raw throughput for smaller models, unified memory systems like the NVIDIA DGX Spark provide the stability needed for the larger 31B dense model.
Consumer GPU Performance (RTX Series)
On a standard RTX 4070 Ti, the Gemma 4 E4B model delivers nearly instantaneous responses. In a coding benchmark, the model was able to plan, structure, and generate a functional Snake game in HTML/JavaScript in approximately 30 seconds. For users with the newer RTX 5090, the gemma 4 inference speed benchmark shows a 2.7x performance lead over Apple's M3 Ultra when using Q4 quantization.
Professional Hardware: DGX Spark (Grace Blackwell)
The DGX Spark, utilizing the GB10 Grace Blackwell Superchip, offers a unique unified memory pool of 122 GB LPDDR5X. While its memory bandwidth is lower than HBM-based datacenter cards (like the H100), its massive capacity allows it to run the 31B model at full BF16 precision without quantization.
| Model (on DGX Spark) | Prompt Processing (pp2048) | Decode / Token Gen (tg128) |
|---|---|---|
| 31B BF16 | 1066 t/s | 3.7 t/s |
| 31B AWQ Int4 | 810 t/s | 10.6 t/s |
| 26B-A4B MoE | 3105 t/s | 23.7 t/s |
💡 Tip: If your workflow requires high-speed interactive chatting, the 26B-A4B MoE model is the clear winner, offering nearly 6.4x better decode throughput than the dense 31B baseline.
The MoE Advantage in 2026
The Mixture-of-Experts (MoE) architecture in Gemma 4 is a game-changer for local inference. Unlike dense models where every parameter is calculated for every token, the 26B-A4B model only "wakes up" about 4 billion parameters per request. This allows the model to reside in memory as a large, knowledgeable entity while performing with the speed of a much smaller model.
In any gemma 4 inference speed benchmark conducted on bandwidth-constrained hardware (like LPDDR5X systems), the MoE model consistently outperforms dense variants. This makes it the ideal candidate for "Navitalk" or "Navibot" style self-hosted solutions where low latency is required for voice-to-text and real-time interaction.
Optimizing for Local Workflows
To get the most out of your hardware, you must choose the correct quantization method. Quantization reduces the precision of the model weights, allowing larger models to fit into smaller VRAM pools while often increasing inference speed.
- AWQ Int4: This is currently the "sweet spot" for 24GB GPUs like the RTX 3090 or 4090. It provides a significant speed boost (up to 3x faster decode) with minimal loss in reasoning quality.
- BF16 (Unquantized): Only recommended if you have 64GB+ of VRAM or are using a unified memory system. This offers the highest accuracy, particularly in the AIME 2026 math benchmarks.
- FP8 KV Cache: Enabling FP8 for the Key-Value (KV) cache is essential for long-context workloads. Gemma 4 supports up to 256,000 tokens, but without FP8 cache, you will quickly run out of memory on documents over 50,000 tokens.
⚠️ Warning: Some early 2026 drivers for the Jetson Orin Nano have reported system freezes when loading the E4B model. Ensure your JetPack OS is updated to the latest version before attempting local inference.
Real-World Utility: Beyond the Numbers
While the gemma 4 inference speed benchmark tells us how fast the model is, its utility is defined by its new native capabilities. Gemma 4 is multimodal across all sizes, meaning it can process images and video out of the box. The smaller E4B and E2B models even include native audio input for on-device speech recognition.
Coding and Debugging
In practical tests, Gemma 4 demonstrates an "internal thinking" process. When asked to build a game, it breaks down the state management and user input logic before writing a single line of code. While it may occasionally fail on complex "one-shot" tasks (such as broken input handling in a game), it excels at self-correction. Providing the model with error logs or describing the bug allows it to reach a working solution in the second iteration.
Strategic Planning
The model is highly effective at structured content generation. When tasked with building a social media strategy, it doesn't just list ideas; it organizes them into pillars, maps them to specific platforms like LinkedIn or TikTok, and creates a logical weekly cadence. This level of organization was previously reserved for much larger, cloud-based models.

FAQ
Q: What is the best hardware for running a Gemma 4 inference speed benchmark?
A: For the 31B dense model, a GPU with at least 24GB of VRAM (like the RTX 3090 or 4090) is recommended using AWQ Int4 quantization. For the best unquantized performance, a DGX Spark or a system with 80GB+ HBM memory is ideal.
Q: Does Gemma 4 support web searching?
A: While the model weights are static, Gemma 4 is designed to use tools. When paired with a local runner like Ollama or Alarma that has web-access enabled, the model can pause, execute a search, and synthesize real-time news into a structured summary.
Q: Why is the 26B MoE model faster than the 31B dense model?
A: The MoE (Mixture of Experts) architecture only uses a fraction of its total parameters (approx. 4B) for each token generated. This reduces the amount of data that needs to be moved through the GPU's memory bandwidth, resulting in significantly higher tokens-per-second.
Q: Can I run Gemma 4 on a laptop?
A: Yes, the Gemma 4 E2B and E4B models are specifically designed for laptops and edge devices. A modern laptop with 16GB of RAM can comfortably run the E4B model for tasks like email drafting, code review, and basic data analysis.
