AMD Unleashes Ryzen 7 9750X and Ryzen 5 9650X: Boosting Zen 5 Speeds to Counter Intel Core Ultra 200S Plus, But at a Cost

A recent leak from chi11eddog suggests an aggressive response from AMD to Intel's upcoming Core Ultra 200S Plus processors. AMD is reportedly preparing two new Zen 5 CPUs, the Ryzen 7 9750X and Ryzen 5 9650X, designed to directly succeed the Ryzen 7 9700X and Ryzen 5 9600X. While built on the same core architecture, these new chips will feature significantly higher clock speeds and, consequently, a dramatically increased Thermal Design Power (TDP).

This strategic shift by AMD raises questions: why commit to nearly doubling the TDP to compete with Intel's new series, which, despite a similar IPC, lags slightly in gaming due to a lack of additional cache? The rationale behind this decision is more nuanced than it appears.

AMD Ryzen 7 9750X & Ryzen 5 9650X: Pushing Zen 5's Mid-Range TDP Envelope

Let's first examine the leaked technical specifications before diving into the strategic implications. On paper, these new chips might seem like less efficient options compared to their predecessors. According to chi11eddog, the Ryzen 7 9750X will feature 8 cores and 16 threads, alongside 32 MB of L3 cache, with a base clock speed of 4.2 GHz and a boost frequency of 5.6 GHz, all within a 120W TDP. Similarly, the Ryzen 5 9650X will sport 6 cores and 12 threads, also with 32 MB of L3 cache, boasting a 4.3 GHz base clock and a 5.5 GHz boost, also rated at 120W TDP.

The significant changes become clear when comparing them to their direct predecessors. The Ryzen 7 9700X had a 3.8 GHz base clock, 5.5 GHz boost, and a 65W TDP. The Ryzen 5 9600X, on the other hand, offered a 3.9 GHz base, 5.4 GHz boost, and also a 65W TDP.

These figures clearly illustrate the aggressive shift. Both new CPUs see a +400 MHz increase in their base clock speeds: approximately a +10.5% jump for the Ryzen 7 9750X (from 3.8 GHz to 4.2 GHz) and a +10.3% increase for the Ryzen 5 9650X (from 3.9 GHz to 4.3 GHz). However, the boost frequency improvements are minimal, around +100 MHz, translating to a mere +1.8% for the Ryzen 7 and +1.9% for the Ryzen 5. This begs the question: why would AMD launch such processors, especially when Intel is stepping up its game?

The most striking detail from the leak is the dramatic jump in TDP from 65W to 120W, an increase of approximately 84.6%. Essentially, AMD is nearly doubling the power consumption to achieve only a roughly 10% increase in base frequency and less than 2% in boost frequency. While this might seem illogical at first glance, there's a strategic rationale.

The explanation lies in sustained performance. A 400 MHz increase in base frequency demands consistently higher voltage and current. Since the boost frequency sees minimal change, it's not the primary driver. AMD's objective here isn't about achieving higher peak clock speeds in short bursts, but rather maintaining elevated frequencies for extended periods, especially during demanding, sustained workloads.

AMD understands that Intel's anticipated gains won't solely be in peak benchmark scores, but more importantly, in the improved FPS (frames per second) in gaming, driven by enhancements across various frequency-dependent areas, particularly internal buses like D2D (Die-to-Die). By maintaining the same core count, cache size, and manufacturing node, AMD is leveraging additional power to remain competitive against the Core Ultra 200S Plus lineup. This isn't about fundamentally improving Zen 5's architecture in these specific SKUs, but rather pushing it to its limits to avoid losing ground to Intel in the crucial mid-range and upper-mid-range segments, especially concerning gaming performance. Given that these particular processors lack 3D V-Cache, which typically helps manage TDP more efficiently, achieving a 400 MHz base clock increase necessitates nearly doubling the power consumption – a strategic trade-off.
