This article covers GAINWARD RTX4070 PHOENIX 12GB グラフィックスボード NED4070H19K9.

Overview

The GAINWARD RTX4070 PHOENIX 12GB (model number NED4070H19K9-1043X-G, VD8473) is a mid-range graphics card built around the NVIDIA GeForce RTX 4070 GPU. Based on the Ada Lovelace architecture, it delivers a significant leap in ray tracing performance and power efficiency over the previous generation. With 12 GB of GDDR6X memory, this card is perfectly suited for 1440p gaming, offering a sweet spot between cost and performance. This model features a factory-boost clock of 2475 MHz and a large 3.1-slot cooling solution to keep temperatures in check under load. Power is delivered via a 12VHPWR (16-pin) connector, and the card includes DisplayPort 1.4a and HDMI 2.1a outputs for up to four displays. It is sold as an officially distributed product in Japan with a one-year warranty, available through major online retailers like .

Compatibility Guide

This graphics card uses a PCI-Express 4.0 x16 interface. It is backward compatible with PCIe 3.0 slots, though a slight performance penalty may occur in bandwidth-sensitive scenarios. The card occupies 3.1 expansion slots, so ensure your motherboard has enough clearance. Physical dimensions are 328.9 mm (length) by 131.1 mm (width) by 63.6 mm (height) — a mid-tower or larger case is recommended. A power supply unit rated at 650W or higher is recommended. The card uses a single 12VHPWR connector; an adapter for two 8-pin PCIe power cables is included. Windows 10/11 and Linux are fully supported with NVIDIA's Game Ready drivers.

Product Info

The GAINWARD RTX4070 PHOENIX 12GB was launched in April 2023 and sits in the mid-range segment of the graphics card market. Pricing fluctuates with market conditions; the current reference price is approximately ¥173,099 (tax included). It is available through and other PC component retailers in Japan, backed by a one-year official warranty. As a mid-range offering, it targets 1440p gaming with high settings, while also capable of comfortable 4K gaming with DLSS upscaling. The RTX 4070 features 5888 CUDA cores, 46 RT cores, and 184 Tensor cores, with a maximum TDP of 200W — notable for its efficiency compared to earlier models.

Best Use Cases

First, this card is ideal for gamers playing at 1440p resolution. With support for real-time ray tracing and DLSS 3 frame generation, it delivers high frame rates in demanding titles like Cyberpunk 2077 or Hogwarts Legacy without breaking the bank. Second, content creators working on video editing (DaVinci Resolve, Premiere Pro) or 3D rendering (Blender) will benefit from the 12 GB VRAM and CUDA acceleration. The card handles medium-sized projects with ease and supports hardware encoding via NVENC. Third, users building a power-efficient system will appreciate the 200W TDP. Compared to higher-tier RTX 40-series cards, the Phoenix runs cooler and quieter, making it a great fit for a balanced, quiet gaming PC.

Things to Consider

Because of its 3.1-slot cooler, this card is too large for compact cases or many Mini-ITX builds. Always check your case's maximum GPU length (330 mm needed) and slot thickness before purchasing. The 12VHPWR power connector may require an upgrade from older PSUs. While an adapter is provided, using an ATX 3.0 compliant power supply is recommended for cleaner cable management and reliability. Compared to the AMD Radeon RX 7800 XT (16 GB), the RTX 4070 has less VRAM but superior ray tracing performance and DLSS image quality. If you primarily play at 4K or need more VRAM for heavy creative workloads, consider stepping up to a 16 GB card. ## Specifications | Item | Specification | |------|---------------| | GPU | NVIDIA GeForce RTX 4070 | | Architecture | Ada Lovelace | | Manufacturing Process | TSMC 4N | | CUDA Cores | 5888 | | RT Cores | 46 (3rd Gen) | | Tensor Cores | 184 (4th Gen) | | Base Clock | 1920 MHz | | Boost Clock | 2475 MHz | | Memory | 12 GB GDDR6X | | Memory Bus Width | 192-bit | | Memory Bandwidth | 504 GB/s | | FP32 Performance | 29.1 TFLOPS | | TDP | 200 W | | Power Connector | 12VHPWR (16-pin) ×1 | | Output Ports | DisplayPort 1.4a ×3, HDMI 2.1a ×1 | | Card Length | 328.9 mm | | Card Width | 131.1 mm | | Card Height | 63.6 mm | | Slot Occupancy | 3.1 slots | | Interface | PCI-Express 4.0 x16 | | Recommended PSU | 650 W | | Warranty | 1 year (official Japan distribution) |
